Decision Based Design

Component level reuse enables retention of value from products recovered at the end of their first lifecycle. Reuse strategies determined at the beginning of the lifecycle are aimed at maximizing this recovered value. Decision based design can be employed, but there are several difficulties in large scale implementation. First, computational complexities arise. Even with a product with a relatively small number of components, it becomes difficult to find the optimal component level decisions. Second, if there is more than one stakeholder involved, each interested in different attributes, the problem becomes even more difficult, due both to complexity and Arrow’s Impossibility Theorem. However, while the preferences of the stakeholders may not be known precisely, and aggregating those preferences poses difficulties, what is usually known is the partial ordering of alternatives. This paper presents a method for exploiting the features of a solution algorithm to address these difficulties in implementing decision based design. Heuristic methods including non-dominated sorting genetic algorithms (NSGA) can exploit this partial ordering and reject dominated alternatives, simplifying the problem. Including attributes of interest to various stakeholders ensures that the solutions found are practicable. One of the reasons product reuse has not achieved critical acceptance is because the three entities involved, the customers, the manufacturer and the government do not have a common ground. This results in inaccurate aggregating of attributes which the proposed method avoids. We illustrate our approach with a case study of component reuse of personal computers.

Argentina is experiencing an expansion of soya and maize cultivation that is pushing the agricultural frontier over areas formerly occupied by native Chaco forest. Subsistance farmers use this dry forest to raise goats and cattle and to obtain a broad range of goods and services. Thus, two very different and non-compatible land uses are in dispute. On the one hand subsistance farmers fostering an extensive and diversified forest use, on the other hand, large-scale producers who need to clear out the forest to sow annual crops in order to appropriate soil fertility. First, the paper looks at how these social actors perceive Chaco forest, what their interests are, and what kind of values they attach to it. Second, we analyze the social-environmental conflicts that arise among actors in order to appropriate forest’s benefits. Special attention is paid to the role played by the government in relation to: (a) how does it respond to the demands of the different sectors; and (b) how it deals with the management recommendations produced by scientists carrying out social and ecological research. To put these ideas at test we focus on a case study located in Western Córdoba (Argentina), where industrial agriculture is expanding at a fast pace, and where social actors’ interests are generating a series of disputes and conflicts. Drawing upon field work, the paper shows how power alliances between economic and political powers, use the institutional framework of the State in their own benefit, disregarding wider environmental and social costs.

The subject of the research is the current state of the fuel and energy complex (FEC) that ensures generation of a significant part of the budget and the innovative development of the economy.The purpose of the research was to establish priority directions for the development of the FEC sectors based on a comprehensive analysis of their innovative and investment activities. The dynamics of investment in the fuel and energy sector are considered. It is noted that large-scale modernization of the fuel and energy complex requires substantial investment and support from the government. The results of the government programs of corporate innovative development are analyzed. The results of the research identified innovative development priorities in the power, oil, gas and coal sectors of the fuel and energy complex. The most promising areas of innovative development in the oil and gas sector are the technologies of enhanced oil recovery; the development of hard-to-recover oil reserves; the production of liquefied natural gas and its transportation. In the power sector, the prospective areas are activities aimed at improving the performance reliability of the national energy systems and the introduction of digital technologies. Based on the research findings, it is concluded that the innovation activities in the fuel and energy complex primarily include the development of new technologies, modernization of the FEC technical base; adoption of state-of-the-art methods of coal mining and oil recovery; creating favorable economic conditions for industrial extraction of hard-to-recover reserves; transition to carbon-free fuel sources and energy carriers that can reduce energy consumption and cost as well as reducing the negative FEC impact on the environment.

Chapter 8 draws attention to meta-governance and how the governing of reforms is affected by how reform processes are organized. The chapter asks how reformers can ensure support for large-scale reforms that are likely to attract profound resistance. The focal point of the chapter is a study of geographical decentralization of central government agencies. The chapter argues that successful meta-governance can be provided for by careful organization of the reform process. The empirical case studied is a large-scale relocation of government agencies in Norway during the early 2000s. In carrying out this reform, the government succeeded against the odds. Most importantly, research has revealed huge constraints on the instrumental control of large-scale reforms in general and of geographical relocation of organizations in particular. Yet, this chapter shows that large-scale reforms can be successfully achieved through careful crafting of the reform organization.

Benefiting from convenient cycling and flexible parking locations, the Dockless Public Bicycle-sharing (DL-PBS) network becomes increasingly popular in many countries. However, redundant and low-utility stations waste public urban space and maintenance costs of DL-PBS vendors. In this article, we propose a Bicycle Station Dynamic Planning (BSDP) system to dynamically provide the optimal bicycle station layout for the DL-PBS network. The BSDP system contains four modules: bicycle drop-off location clustering, bicycle-station graph modeling, bicycle-station location prediction, and bicycle-station layout recommendation. In the bicycle drop-off location clustering module, candidate bicycle stations are clustered from each spatio-temporal subset of the large-scale cycling trajectory records. In the bicycle-station graph modeling module, a weighted digraph model is built based on the clustering results and inferior stations with low station revenue and utility are filtered. Then, graph models across time periods are combined to create a graph sequence model. In the bicycle-station location prediction module, the GGNN model is used to train the graph sequence data and dynamically predict bicycle stations in the next period. In the bicycle-station layout recommendation module, the predicted bicycle stations are fine-tuned according to the government urban management plan, which ensures that the recommended station layout is conducive to city management, vendor revenue, and user convenience. Experiments on actual DL-PBS networks verify the effectiveness, accuracy, and feasibility of the proposed BSDP system.

The reliability of photovoltaic (PV) generators is strongly affected by the performance of Direct Current/Alternating Current (DC/AC) converters, being the major source of PV underperformance. However, generally, their reliability is not investigated at component level: thus, the present work presents a reliability analysis and the repair activity for the components of full bridge DC/AC converters. In the first part of the paper, a reliability analysis using failure rates from literature is carried out for 132 inverters (AC rated power of 350 kW each) with global AC power of 46 MW in a large scale grid-connected PV plant. Then, in the second part of the work, results from literature are compared with data obtained by analyzing industrial maintenance reports in the years 2015–2017. In conclusion, the yearly energy losses involved in the downtime are quantified, as well as their availability.

The Impact

Confronting an energy crisis, the government of Ghana enacted a power factor correction policy in 1995. The policy imposes a penalty on large-scale electricity users, namely, special load tariff (SLT) customers of the Electricity Company of Ghana (ECG), whose power factor is below 90%. This paper investigates the impact of this policy on these firms’ power factor improvement by using panel data from 183 SLT customers from 1994 to 1997 and from 2012. To avoid potential endogeneity, this paper adopts a regression discontinuity design (RDD) with the power factor of the firms in the previous year as a running variable, with its cutoff set at the penalty threshold. The result shows that these large-scale electricity users who face the penalty because their power factor falls just short of the threshold are more likely to improve their power factor in the subsequent year, implying that the power factor correction policy implemented by Ghana’s government is effective.

In its program for underdeveloped areas, the United Nations faces on a large scale the need to effect concrete adaptations of the habits of indigenous peoples to modern knowledge and technology. Research to determine the best methods of procedure has disclosed that, in certain areas, previous attempts on the part of administrators to introduce innovations and make changes which could not be integrated into the cultural pattern of the indigenous people proved unsatisfactory to them and costly to the government concerned. In most cases, changes in diet, crops and habits of work—let alone the introduction of industrial disciplines—may not be pressed down like a cookie-cutter on a going society. The administration of change often proves a disconcertingly stubborn affair, exasperating both to the administrator and to the people whom he seeks to catch up into the ways of "progress."

Development process in Odisha (before 2011 Orissa) may have led to progress but has also resulted in large-scale dispossession of land, homesteads, forests and also denial of livelihood and human rights. In Odisha as the requirements of development increase, the arena of contestation between the state/corporate entities and the people has correspondingly multiplied because the paradigm of contemporary model of growth is not sustainable and leads to irreparable ecological/environmental costs. It has engendered many people’s movements. Struggles in rural Odisha have increasingly focused on proactively stopping of projects, mining, forcible land, forest and water acquisition fallouts from government/corporate sector. Contemporaneously, such people’s movements are happening in Kashipur, Kalinga Nagar, Jagatsinghpur, Lanjigarh, etc. They have not gained much success in achieving their objectives. However, the people’s movement of Baliapal in Odisha is acknowledged as a success. It stopped the central and state governments from bulldozing resistance to set up a National Missile Testing Range in an agriculturally rich area in the mid-1980s by displacing some lakhs of people of their land, homesteads, agricultural production, forests and entitlements. A sustained struggle for 12 years against the state by using Gandhian methods of peaceful civil disobedience movement ultimately won and the government was forced to abandon its project. As uneven growth strategies sharpen, the threats to people’s human rights, natural resources, ecology and subsistence are deepening. Peaceful and non-violent protest movements like Baliapal may be emulated in the years ahead.

The development of Russian foreign trade during the previous five years is analyzed. It is stated that, in terms of value, exports of services and imports of goods and services steadily grew during the first four years of the period under review. Exports of goods also rose during three years, but in 2014 both exports and imports again fell in comparison with the previous year as was the case five years ago. The composition of the Russian exports and imports of goods did not change radically during the previous years. The main items of export are, as always, mineral products, metals and fertilizers. Import is prevailed by foodstuffs, chemicals and heavy engineering equipment. The current situation is featured by the reduction of world oil prices, slump of the domestic economy and war of sanctions with the Western countries. All this substantially impairs the conditions of Russia’s foreign trade activities and inhibits its development in the upcoming years. In the author’s view, the implementation of measures worked out by the government – correction of tariff liabilities before the WTO, redirecting of trade streams from the European to the Asian markets, import substitution and export support – will unlikely improve the situation. Revision of the liabilities before the WTO in the conditions of the decrease of the internal demand and serious devaluation of Ruble is considered as inappropriate and counterproductive. “Asiatic turn” is only capable to compensate to a certain respect the loss of supplies of some food products from Europe, but cannot fully offset the loss of potentialities of the acquisition of modern technologies and equipment from the developed countries. It is doubtful that it will be possible to dramatically cut the import dependence. It is necessary to replace many kinds of foreign goods, but it is impossible to implement a frontal substitution of import in all directions. Excessive stress on the import substitution might lead to the emergence of shortages and poorer availability of some goods at the internal market and, at the worst, to self-isolation and economic autarky. The attempts to build up an effective system of export support might be successful only in the conditions of the establishment of the large-scale production of goods and services which would be comparable with the foreign analogues in respect to the criteria of price and quality. Taking this into consideration the technological renovation of production processes, first of all in the manufacturing industry, and on this basis rising up of the competitiveness of plants and factories are the most important prerequisites for encouraging export activities and formation of the new export specialization of the country.
