In a cell production system, a number of machines that differ in function are housed in the same cell. The task of these cells is to complete operations on similar parts that are in the same group. Determining the family of machine parts and cells is one of the major design problems of production cells. Cell production system design methods include clustering, graph theory, artificial intelligence, meta-heuristic, simulation, mathematical programming. This article discusses the operation of methods and research in the field of cell production system design. Methodology:To examine these methods, from 187 articles published in this field by authoritative scientific sources, based on the year of publication and the number of restrictions considered and close to reality, which are searched using the keywords of these restrictions and among them articles Various aspects of production and design problems, such as considering machine costs and cell size and process routing, have been selected simultaneously.Findings: Finally, the distribution diagram of the use of these methods and the limitations considered by their researchers, shows the use and efficiency of each of these methods. By examining them, more efficient and efficient design fields of this type of production system can be identified.Originality/Value: In this article, the literature on cell production system from 1972 to 2021 has been reviewed.
Today, the development of appropriate strategies as one of the basic tools of companies to compete in the markets of the e-commerce era. The strategy formulation process is inelastic with common strategic management models such as balanced scorecard and SWOT model in the face of market changes and competitive behaviour of competitors. It becomes. In this article, after reviewing the general structure of strategy formulation using the balanced scorecard model, the mentioned shortcomings in the strategy formulation process are examined. In the field of purposeful design, competitive strategies are presented and finally, the use of Judo Strategy model, SWOT matrix and Balanced Scorecard model of SJB framework is presented as an agile and systematic model in the process of designing and formulating strategy. In order to evaluate the applicability of this model, the beta company has been selected and with the cooperation of the top managers of that company, the proposed model has been implemented in the process of designing and formulating its strategy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
