Cellular manufacturing system (CMS) is highly important in modern manufacturing methods. Given the ever increasing market competition in terms of time and cost of manufacturing, we need models to decrease the cost and time of manufacturing. In this study, CMS is considered in condition of dynamic demand in each period. The model is developed for facing dynamic demand that increases the cost of ...

In recent years Cellular Manufacturing has become an effective tool for improving productivity. Attainment of full benefits of Cellular Manufacturing depends firstly on the design of the machine cells and part families, secondly on the method of operations which takes full advantage of cell properties. Inappropriate methods of loading and scheduling can even lead to the failure of the Cellular ...

In this paper a multi-objective nonlinear programming model of cellular manufacturing system is presented which minimize the intercell movements and maximize the sum of reliability of cells. We present a genetic approach for finding efficient solutions to the problem of cell formation for products having multiple routings. These methods find the non-dominated solutions and according to decision...

The converting process from traditional production systems (e.g., Job Shops) to focused (cellular) systems is important as one requirement of global manufacturing to challenge the existing global financial crisis. This represents a big problem and a huge task for manufacturers and academicians which almost most of industrial enterprises around the world are still working as a job shop. This con...

In this research paper cellular manufacturing is discussed under conditions of changing product demand. Traditional cell formation procedures ignore any changes in demand over time from product redesign and other factors. However given that in today‟s business environment, product life cycles are short, a framework is proposed that creates a multi-period cellular layout plan including cell rede...

There are essentially two ways to implement a Cellular Manufacturing System (CMS): physical and logical. In the first case, the machines are laid out in the floor space in dedicated manufacturing cells to exploit flow shop efficiency in processing part families, whereas in the second case machines are dedicated to process part families in a process layout. Logical oriented CMS are known as Virt...

    Dynamic cellular manufacturing systems,   Mixed-integer non-linear programming,   Production planning, Manufacturing attributes   This paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (DCMS) based on production planning (PP) decisions and several manufacturing attributes. Such an integrated DCMS model with an extensi...

This paper presents a new, bi-criteria mixed-integer programming model for scheduling cells and pieces within each cell in manufacturing cellular system. The objective of this is to minimize the makespan inter-cell movements simultaneously, while considering sequence-dependent setup times. In CMS design planning, three main steps must be considered, namely formation (i.e., piece families machin...
