An Efficient Algorithm to Inter and Intra-Cell Layout Problems in Cellular Manufacturing Systems with Stochastic Demands

DYNAMIC COMPLEXITY OF A THREE SPECIES COMPETITIVE FOOD CHAIN MODEL WITH INTER AND INTRA SPECIFIC COMPETITIONS

The present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. The behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. Boundedness and dissipativeness of the system are e...

Robust optimization of a mathematical model to design a dynamic cell formation problem considering labor utilization

Cell formation (CF) problem is one of the most important decision problems in designing a cellular manufacturing system includes grouping machines into machine cells and parts into part families. Several factors should be considered in a cell formation problem. In this work, robust optimization of a mathematical model of a dynamic cell formation problem integrating CF, production planning and w...

Design of Dynamic Distributed Layouts

We develop a procedure for the design of distributed layouts in a multiple period setting, where product demand and product mix may vary from period to period. We allow for multiple copies of the same department type to be placed in non-adjoining locations and for flow allocation among department duplicates to be made based on the demand for each period. We also allow for the possibility of a r...

Performance Analysis of Dynamic and Static Facility Layouts in a Stochastic Environment

In this paper, to cope with the stochastic dynamic (or multi-period) problem, two new quadratic assignment-based mathematical models corresponding to the dynamic and static approaches are developed. The product demands are presumed to be dependent uncertain variables with normal distribution having known expectation, variance, and covariance that change from one period to the next one, randomly...
