The Impact

Produk pertanian dikategorikan sebagai produk yang mudah rusak, produk dengan waktu hidup yang singkat, membutuhkan perencanaan dan penanganan yang tepat untuk mengurangi kerugian yang disebabkan oleh waktu hidupnya. Beberapa penelitian tentang sistem distribusi produk yang mudah rusak telah dilakukan. Banyak penelitian sebelumnya berfokus pada pasar terstruktur (pasar modern atau ekspor). Di sisi lain, permintaan pasar lokal selalu ada dan memiliki proporsi permintaan pertanian yang signifikan. Studi ini bertujuan untuk mengidentifikasi karakteristik produk yang mudah rusak dari rantai pasokan lokal sebagai dasar untuk merancang sistem distribusi untuk meningkatkan efisiensi logistik. Desain rantai pasokan dikembangkan dengan menggunakan studi kasus pada sayuran (bayam, kangkung, dan sawi) yang diproduksi dari Tumpang, salah satu daerah penghasil sayuran terbesar di Malang. Wilayah distribusi penelitian ini terbatas pada wilayah Malang Raya. Namun, model yang dihasilkan dalam penelitian ini dapat digunakan untuk cakupan distribusi yang lebih luas. Hasil dari penelitian ini adalah pemetaan proses dalam rantai pasokan sayuran, rantai pasokan model konseptual sayuran, dan model simulasi sistem distribusi dari tingkat petani ke pasar grosir. Hasil pemetaan aktor dan karakteristik rantai pasokan menunjukkan proses dan tahapan yang panjang dalam waktu hidup produk yang singkat (dalam satu hari produk harus diterima oleh konsumen), terutama dalam jalur distribusi ke pasar lokal. Berdasarkan hasil simulasi sistem distribusi, untuk mendapatkan proses pengiriman yang lebih efisien diperlukan lebih banyak truk. Namun, dampak truk tambahan adalah investasi yang lebih dibutuhkan. Investasi truk yang didanai sendiri akan memakan waktu hampir empat tahun untuk satu truk tambahan. Skenario yang diusulkan adalah truk outsourcing, yang dapat mengurangi frekuensi proses pengiriman, dan mengurangi biaya hingga 24,02%. Skenario lain juga dapat dianalisis menggunakan model ini. Skenario, termasuk proporsi penanaman, siklus tanam, skenario harga, jenis truk, dan rute pengiriman dari pasar sayuran pusat ke pasar grosir. Pengembangan model simulasi juga dapat dilakukan dengan menambahkan lebih banyak variabel seperti faktor penanganan dalam proses pengiriman dan siklus faktor waktu tanam.   The agriculture product is categorized as perishable product, products with a short life time, requiring proper planning and handling to reduce the losses caused by its life time. Some research on perishable product distribution system have been done. Many of the previous researches focused on structured market (modern market or exports). On the other hand, the demand of local market is constantly exist and has a significant proportion of agriculture demand. This study aims to identify the characteristics of the local supply chain perishable products as the basis for designing the distribution system to improve the efficiency of logistics. Supply chain design is developed by using case study on vegetables (spinach, kale, and mustard greens) produced from Tumpang, one of the largest vegetable producer area in Malang. The distribution area of this study is limited to the area of Malang Raya. However, the model generated in this study can be used for a wider distribution coverage. The results of this study are processes mapping in the supply chain of vegetables, conceptual model vegetable’ supply chain, and simulation model of distribution system from farmer level to the wholesale market. The mapping result of actors and characteristics of the supply chain show the long processes and stages within the short product life time (in one day the product must be received by the consumer), especially in the distribution line to local market. Based on distribution system simulation results, to have more efficient delivery process require more trucks. However, the impact of additional trucks are more investment needed. Self-funded investment of truck will take almost four years for one additionl truck. The proposed scenario is outsourced trucks, which are able to reduce the frequency of delivery process, and reduce cost up to 24.02%. Other scenarios can also be analyzed using this model. The scenarios, including proportion of planting, planting cycles, price scenarios, type of truck, and the delivery route from central vegetable market to the wholesale market. Development of a simulation model is also can be done by add more variables such as handling factor in the delivery process and the cycle of planting time factor.

Эксплуатация морского транспорта подвержена влиянию множества факторов, учет которого требует высокой трудоемкости. Как правило, моделирование морских транспортных систем, выступающих в роли связующего звена различных экономических процессов, производится на стадии предпроектной разработки. На этой стадии, помимо прочего, необходимо оценить влияние на проектируемую систему не только детерминированных, но и стохастических процессов. В данной работе описан алгоритм учета влияния ветро-волновых режимов морских участков на эксплуатацию морских транспортных судов. Данный алгоритм реализован на примере модели системы поставок сжиженного природного газа (СПГ) морским транспортом потребителям г. Мурманск. Научной новизной данной работы является комплексный подход к логико-математическому описанию эксплуатации морских транспортных средств. Этот подход включает в себя моделирование эксплуатации судна на базе агентного подхода, моделирование ветро-волновых режимов на основе анализа временных рядов и стохастических экспериментов и определение скорости движения судна на основе эмпирико-статистических формул расчета скорости судна и теории гидродинамики судна. В ходе выполнения данной работы была построена имитационная модель поставок СПГ в г. Мурманск морским транспортом. Результаты прогонов этой модели были верифицированы на основе технико-экономического обоснования АО «ЦНИИМФ». Алгоритм построения имитационной модели, описанный в данной работе, может быть применен для имитационного моделирования морских транспортных систем с различными целями функционирования. Marine transport operation is affected by a lot of factors taking into account of which requires a high laboriousness. In most cases modelling of marine transport operation as a link in various economic processes is performed at the pre-design development stage. By the way, evaluation of the impact of both deterministic and stochastic processes on the designed system is necessary at this stage. Evaluation of transport system efficiency based on pre-formed system of criteria is in progress at this stage. This paper describes an algorithm for modeling the operation of marine vessels taking into account wind-wave regime of sea areas. This algorithm is implemented by the model of liquified natural gas (LNG) supply chain system by marine transport to consumers of the city of Murmansk. Scientific novelty of this paper is a complex approach to logical-mathematical description of marine vehicles exploitation. This approach consists of agent-based simulation of vessel exploitation, modelling of wind-wave regimes by means of time series analysis and stochastic modelling and the speed determination of the vessel movement based on the empirical-statistical formulas for calculating the speed of the vessel and the theory of vessel hydrodynamics. During this research simulation model LNG supply chain system by marine transport to consumers of the city of Murmansk was developed. The results of the model have been verified by the feasibility study performed by CNIIMF JSC. The algorithm for constructing simulation model described in this paper could be implemented in modelling of marine transport system for various purposes.

The Impact

Purpose The purpose of this paper is to evaluate the financial and material flows in cash-based responses (CBRs) and their implications for humanitarian operations. This research proposes to view cash as a commodity used by humanitarian actors in emergency operations and therefore aims to explore how CBRs impact on humanitarian logistics and ultimately, affect beneficiaries. Design/methodology/approach The methodological approach of grounded theory was chosen for this inquiry because it allowed the researchers to generate a general explanation for the process of CBRs in emergency situations based on the views of participants interviewed. Interviews were conducted with senior managers, supply chain managements and logistics officers from international humanitarian organisations (HOs), United Nations agencies and commercial organisations involved in humanitarian operations. Examples of topics covered during the field work included, procedures and policy; knowledge and information management; systems and technology; actors and agents. Findings The impact of CBRs on humanitarian operations can though not be understated. They alter supply chain design, the very role of beneficiaries as well as HOs, and change the strategy of aid delivery from push to pull. Perhaps, the most important factor is the elimination of many logistical activities that needed to be performed by HOs. Delivering cash diminishes the needs for lengthy procurement and assessment processes, pre-positioning, transportation and distribution. This bears the potential of significant reductions in costs for delivering humanitarian aid at the same time as it is an important move from aid to trade. Practical implications The challenge for humanitarian agencies in the coming years is to overcome their fears surrounding CBRs, and to implement cash programmes where they are judged to be the most appropriate response. This will require not only a change in donor policies, but also a fundamental change in the skill set of humanitarian logisticians, who are used to identifying needs and providing commodities and thus to maintaining control over the provision of assistance. Originality/value The contribution of this research is twofold: this is the first examination of cash-based interventions in humanitarian operations through the prism of supply chain management. Second, the research is field based and grounded in empirical observations thus adding to the literature and offering insights to practice.

The Impact

Although the development of supply chain management trends has been the subject of substantial research, little attention has been devoted to examining the impact of the emerging supply chain management (SCM) trends on the spatial organization of the supply and distribution system. Specifically, the literature lacks an integrated methodological framework for examining the impact of emerging SCM trends on decision making relative to the spatial organization of logistical networks. This analysis has three purposes—( a) develop a conceptual framework for analyzing how decisions are made on the spatial organization of logistical networks, ( b) test the proposed framework via case studies, and ( c) develop a preliminary set of guidelines on the essential elements in making strategic logistical network design decisions. An interesting finding in implementing the proposed methodological framework, which was further supported by the limited empirical research, is that decision-making requirements vary substantially among the industrial and service sectors. This variance reflects differences in objectives and the extent of integration and collaboration of business entities along the respective supply chains.

The Impact

In the food retail industry, the agility and responsiveness of the supply chain are crucial because demand is volatile and short lead times are mandatory. The logistics performance is of critical importance to provide a high level of efficiency in operations and a high degree of customer satisfaction. The Handling Unit, or the minimum quantity to send to retail stores (the ship-pack), is a factor of considerable influence on logistics efficiency and costs. In this work, it was developed a simple analytical cost model for a Portuguese food retail two-tier distribution system (distribution centre and store) to support the evaluation of the conversion of the handling unit to half-pallet. The results of the model, considering a pilot study with three scenarios, suggest an economic gain of approximately 75% (comparatively to the current situation) in logistics costs. These quantitative results were decisive to guide decision-makers.

Organizations are operating in an environment which offers opportunities but also dangers, risks, changes, and challenges. To face these changes, organizations must develop effective strategies based on relationships with stakeholders and profit decisions, and cost-based in order to obtain competitive advantage. To satisfy customers' needs, the organizations seek a position of superiority over its competitors. To deploy its activities and to achieve its objectives, any organization must dispose resources such as material, human, financial, informational, and technological. This chapter treats a very interesting theme, that of procurement, as commercial activity, in the complex activities of organizations. The chapter starts with the literature in the field and presents the evolution of the process, the objectives, the roles, the functions, the activities, and the typology. The author presents the impact the new technologies have on procurement process, using a simulation model, based on mathematical and statistical models and IT programs.

The paper demonstrates the need to consider different sustainability aspects in supply chain redesign and optimization problems. To this end a simulation model of local pharmaceutical business retail is presented as application example. Three different sustainability aspects are considered (technical sustainability, economic sustainability and environmental sustainability) when investigating two different problems: the addition of new pharmacies to the supply chain and optimization of the supply chain routes. The main goals are to understand how new potential customers can be added to the supply chain while reducing the negative impact on the customers’ satisfaction level (technical sustainability), how to optimize the routes followed by each transportation vector (technical, economic and environmental sustainability) and how to compare different solutions in terms of truck fleets in order to reduce CO2 emissions (environmental and economic sustainability).

Sourcing Strategy

Purpose – The purpose of this paper is to assess whether an existing sourcing strategy can effectively supply products of appropriate quality with acceptable levels of product waste if applied to an international perishable product supply chain. The authors also analyse whether the effectiveness of this sourcing strategy can be improved by including costs for expected shelf life losses while generating order policies. Design/methodology/approach – The performance of sourcing strategies is examined in a prototype international strawberry supply chain. Appropriate order policies were determined using parameters both with and without costs for expected shelf life losses. Shelf life losses during transport and storage were predicted using microbiological growth models. The performance of the resulting policies was assessed using a hybrid discrete event chain simulation model that includes continuous quality decay. Findings – The study's findings reveal that the order policies obtained with standard cost parameters result in poor product quality and large amounts of product waste. Also, including costs for expected shelf life losses in sourcing strategies significantly reduces product waste and improves product quality, although transportation costs rise. Practical implications – The study shows that in perishable product supply chain design a trade-off should be made between transportation costs, shortage costs, inventory costs, product waste, and expected shelf life losses. Originality/value – By presenting a generically applicable methodology for perishable product supply chain design, the authors contribute to research and practice efforts to reduce food waste. Furthermore, product quality information is included in supply chain network design, a research area that is still in its infancy.

The Impact

This paper aims to develop a new bi-level game model for joint pricing and inventory decisions in a competitive supply chain consisting of a dominant manufacturer, who produces single perishable product from deteriorating raw materials, and two follower retailers who face nonlinear price-dependent demand and operate under Cournot assumptions. Three levels of warehousing including raw material warehouse, final product warehouse, and retail warehouses with exponential deterioration rates are considered to explore the joint impact of deterioration rate and price elasticity on the equilibrium inventory decisions. A Stackelberg-Nash-Cournot model is developed to seek the equilibrium prices, quantities, and replenishment cycles and is solved through an exact methodology. A numerical example is presented to validate the proposed model and comprehensive sensitivity analyses are carried out to measure the impact of the model’s key parameters including the deterioration rate in the producer’s and the retailers’ warehouses, the retail and competitor price elasticity, and the market scale on the equilibrium.
