Downtime has been considered as the most significant contributor to system inefficiency in manufacturing industry. During a downtime, the stoppage at the downtime machine will lead to impact on system production. In addition, it will also change system buffer levels, and thus alter system future behavior, which may lead to impact on system production in future time. For each downtime, a complete evaluation of its production impact during and after the downtime is important for deciding where to allocate limited resources for improving system production. However, the evaluation of downtime impact on system future production has not been studied. Motivated by this need, we investigate how each downtime would change the buffer levels and impact system production in the future. The concept of downtime settling time is proposed to reflect such impact. Given the downtime list, an analytical method is developed to estimate this impact of each downtime. Case studies are conducted to demonstrate the accuracy and effectiveness of the proposed methods.

Traditional Construction

The growing context of globalization permanently increases pressure on the construction companies to improve their performances in order to resist to the constraints of competitiveness in the international market. It has become ineluctable to look for introducing a new alternative capable of bringing creative improvement to the traditional production system. This paper will relate mainly to the most relevant management techniques in the construction industry, and more specifically, the lean construction concept. Initially, we will determine the main characteristics of the construction industry compared to the manufacturing industry according to three levels: on-site production, one of a kind projects, and complexity. Subsequently, we will focus our attention on the main sources of waste in the construction industry. Finally, a rigorous comparative study will be carried out to show the contribution of the lean construction tools in the promotion of traditional construction especially at the level of the following factors: Creating value and eliminating waste; Planning and mutual coordination; Site organization. Lean construction as Last Planner System (LPS), Value Stream Mapping (VSM), Just-in-Time philosophy, Visual management (VM) and 5S have shown a great ability to improve the traditional production system through waste reduction, encouraging people involvement, ensuring a pull flow production, and promotion of a continuous improvement philosophy.

Purpose The purpose of this paper is twofold: first, to explore the relationship between success parameters and implementation of advanced manufacturing technology (AMT); and second, to examine the changes required in manufacturing system as a result of AMT implementation. Design/methodology/approach The first order confirmatory factor analysis was performed to validate the presence of observed variables on their respective latent variable. Structural equation modeling is used to test the considered eight hypotheses. Findings The finding indicates that all five success factors are positively related to the AMT implementation. The redesign in the production system and organization strategy is directly related to the AMT implementation. The notable finding is the AMT implementation has no direct impact on the redesign of human resource, but it has mediated impact through the production system. Research limitations/implications The originality and reliability of data collected for research purpose merely depends upon information and the accessible resources. Originality/value The outcome of the present work gives rise to meaningful implications for researchers and practitioners as well.

The increasing competition in the manufacturing industry caused increasing inconsumer demand of the quality and quantity of a good product. Therefore, manufacturing companies must have reliable services, policies and product qualities to satisfy its customers. So it needs to be supported by efficient production system and inventory system. To able to create an efficient production system then need a good raw material inventory planning. This research aims to compere how efficiently in planning raw materials inventory between Wagner-Within Algorithm with the actual concept that applied to PT X, Sidoarjo. The methodology of this research is qualitative descriptive research. The findings this research is engaged in packaging (woven bag and jumbo bag) with main raw materials such as plastic ore and supporting material in inner, thread, additive, and pigment. Based on the result of the analysis is known that the actual concept of the company gives the total inventory cost IDR 3.151.000.000 with the frequency of ordering 12 times while WagnerWithin Algorithm method provides a more efficient total inventory cost of Rp. 2.685.821.101 with8 times the frequency of ordering and can savings of 14.8% of total raw material inventory cost.

This article discusses the importance of lean product development in the manufacturing industry. Lean manufacturing is a concept developed by Toyota more than 30 years ago. It was motivated by the desire to build better and more innovative products with lower costs. The result was the evolution of what is commonly known as the Toyota production system. This system increases efficiency and reduces waste in each area of the production process by eliminating unnecessary efforts and empowering all levels of the workforce. Lean product development is based on the theory of lean manufacturing. The processes focus on simplicity and effectiveness. Lean product development allows for communication between multi-departmental teams, simplifying and keeping the development process moving forward. Using lean product development to manage projects puts accountability on the project owners.

Improve Production Efficiency

Since modern production system is a highly complicated discrete manufacturing system, it is very difficult to design the production line by traditional means. However, through building model of production system in virtual environment, analyzing and evaluating production system performance based on system simulating technology, the production system’s parameter and configuration can be optimized ahead of production plan to optimize production process and improve production efficiency. In this paper, the main shaft production line simulation model is constructed based on the object oriented discrete system software eM-Plant. The production line throughput, utilization and bottleneck operations are analyzed. Based on this, it can support the configuration of production line optimized. The example verifies that the modeling and simulation technology could be successfully used in manufacturing industry.

Recently, there have been done numerous investigations related to lean manufacturing techniques. However, very little has been reported about the implementation and selection of lean manufacturing in the Kosovo manufacturing industry. This article presents the application of lean tools through Kosovo manufacturing industries and the selection of the most useful lean techniques for developing a model for an innovative smart Kosovo enterprise which is our initiative in the process of preparing Kosovo enterprises for the new age of industry—Industry 4.0. After several visits through Kosovo enterprises, the literature review has noticed that there is no investigation in the selection and implementation of lean techniques and tools in Kosovo enterprises. The purpose was to understand how Kosovo manufacturing enterprises use lean techniques and which are the most useful techniques. Analyses have been done based on interviews and questionnaires. Seven basic lean techniques are selected based on the response from the questionnaire and representing basic lean tools for developing a model of a production system regarding Industry 4.0.

Major Trend

In recent years, outsourcing has become a major trend with more and more companies contracting work out to 3rd parties. The aircraft giant—Boeing company，also regards outsourcing as an important way of its production process. In 2003, under the influence of Toyota production system(TPS),Boeing adopted a new manufacturing model to produce the airplane—Boeing 787 Dreamliner. It outsourced more than 70% of the development and production of its aircraft under a 3-Tier system .However, the excess outsourcing has caused lots of problems such as communication issues, lengthy delays and unexpected increased costs. Starting from the practice of Boeing 787 project's global supply chain strategy, this paper analyzes the reasons as well as problems faced by Boeing for outsourcing such a big project, and draw some lessons on how to strengthen the management from the failure of Boeing 787’s early outsourcing stage.
