To construct and understand the fundamental of relationships among elements in complicated systems on the base of expert(s) opinions, using interpretive structural modeling (ISM) methodology is beneficial. In this paper, for considering consistency rate of expert(s) and obtaining hierarchy of elements (without any loop), a modified ISM method is proposed . These experts have agreement to each...
Piston plays a vital role in almost all types of vehicles. The present study discusses the behavioral study of a piston manufacturing plant. Manufacturing plants are complex repairable systems and therefore, it is difficult to evaluate the performance of a piston manufacturing plant using stochastic models. The stochastic model is an efficient performance evaluator for repairable systems. In...
We discuss the application of economic coordination mechanisms to scheduling problems in manufacturing and logistics. We use job shop scheduling as a sample problem domain. We study economically augmented job shop problems (EJSP) which comprise valuation information. We demonstrate how instances of EJSP can be mapped to combinatorial job shop auction problems (CJSAP). A discussion of the tracta...
A large body of both theoretical and empirical literature has affirmed a positive impact of human capital accumulation in the form of health on economic growth. Yet Baumol (1967) has presented a model in which imbalances in productivity growth between a ‘progressive’ (manufacturing) sector and a ‘nonprogressive’ sector of the economy (of which health care forms an integral part) lead to perpetu...
The purpose of the paper is to analyze the impact of mergers and acquisitions (M&A) sales on economic growth. The analysis is conducted by sectors: primary, manufacturing and services. M&A sales are disaggregated by sectors and also into domestic and cross-border M&A sales. The group of the OECD countries is examined. After applying a Generalized Method of Moments (GMM) estimator, which control...
The aims of the research are to present a model of environmental performance by measuring the effects of a firm’s green practice in conjunction with inter-functional coordination mechanisms, and in turn, measure how environmental performance influences firms’ economic performance. Moreover, this study synthesizes both ecological modernization theory (EMT) and complementarity theory (CT) as a th...
We propose a Multi-Agent framework to analyze the dynamics of organizational survival in cooperation networks. Firms can decide to cooperate horizontally (in the same market) or vertically with other firms that belong to the supply chain. Cooperation decisions are based on economic variables. We have defined a variant of the density dependence model to set up the dynamics of the survival in the...
Nowadays, flexible manufacturing system (FMS) is introduced as a response to the competitive environment. Scheduling of FMS is more complex and more difficult than the other scheduling production systems. One of the main factors in scheduling of FMS is variable time of taking orders from customers, which leads to a sudden change in the manufacturing process. Also, some problems are created in p...
The perspectives on the manufacturing footprint of global firms are widening from the economic aspects to also include the environmental and social aspects. Thus, sustainability is becoming an important issue for the location of manufacturing facilities. It is therefore timely to review the relevant aspects and dimensions in the extant literature to investigate the relationship between sustaina...
This paper investigates the interaction between the economics of production and imperfections in the production process. SpeciÞcally, this paper is the Þrst to devise a model in an attempt to provide managers with guidelines to choose the appropriate production run times to buffer against both the production of defective items and stoppages occurring due to machine breakdowns. In addition to pr...
