This study examines the robust facility layout problem (RFLP) while taking into account unpredictable health and environmental safety standards. problem's major goal is to arrange departments in various of a hall, allot each department appropriate amount space, identify kind amenities equipment needed for chosen sector. To accomplish aforementioned objective, five criteria were taken account: t...

Cellular manufacturing (CM) is one of the most important subfields in the design of manufacturing systems and as a recently emerged field of study and practice, virtual cellular manufacturing (VCM) inherits the importance from CM. One type of VCM problems is VCM with alternative processing routes from which the route for processing each part should be selected. In this research, a bi-objective ...

In this paper, a robust optimization approach is proposed to design a dynamic cellular manufacturing system (DCMS) under uncertainty of processing time of products. In addition, a mathematical model considering cell formation, inter-cell design and production planning under a dynamic environment (i.e., product mix and demand are changed in each period) is presented. Therefore, reconfiguration b...

In this paper, systematic mismatch due to parameter gradients is modeled and analyzed. A new layout strategy with flexible cell placement is proposed. Theoretical analysis shows its property of canceling the mismatch between two devices due to up to n order gradient effects by using 2 unit cells for each device. Simulation results show that the proposed technique gives better matching character...

This paper studies the device variability influence on 6T-SRAM cells in a function of the regularity level of their layout. Systematic and random variations have been analyzed when these memory circuits are implemented on a 45 nm technology node. The NBTI aging relevance on these cells has been also studied for two layout topologies and SNM has been seen as the parameter that suffers the highes...

A set of CAD tools for the synthesis and layout generation of multiple-valued current-mode CMOS logic (CMCL) circuits is described. The synthesis method is based upon the cost-table method. The general circuit structure, the cost-table functions and the decomposition procedure used in the cost-table synthesis program are explained. The synthesis program is based upon a logically complete set of...

Integrated applications for solar energy production becomes increasingly important. The electrification of car bodies and building facades are only two prominent examples. In such shading a challenging problem, since the classic serial interconnection cells in terms power output is highly vulnerable to partial shading. this article, we investigate three most common module layouts market (conven...
