In this paper, a mixed-integer linearized programming (MINLP) model is presented to design a group layout (GL) of a cellular manufacturing system (CMS) in a dynamic environment with considering production planning (PP) decisions. This model incorporates with an extensive coverage of important manufacturing features used in the design of CMSs. There are also some features that make the presented...

A fuzzy linear programming approach is taken to solve an extended mathematical linear programming model to handle two important problems in cellular manufacturing systems simultaneously: Cell formation and layout design. We seek to minimize the total cost of inter-cell and intra-cell (forward and backward) movements and the cost of machines. The fuzzy demand and fuzzy machine capacity are also ...

In this paper, we present a nanometric layout generation tool for analogue building blocks called devices. We focus on the procedural routing methods inside devices. A device may have one or more folded transistors’ fingers merged into at least one stack depending on the chosen layout style. We present two routing methods: intra-stack and inter-stack to ease the routing of the wired segments. T...

BACKGROUND Optune™, previously known as the NovoTTF-100A System™, generates Tumor Treating Fields (TTFields), an effective anti-mitotic therapy for glioblastoma. The system delivers intermediate frequency, alternating electric fields to the supratentorial brain. Patient therapy is personalized by configuring transducer array layout placement on the scalp to the tumor site using MRI measurements...

In order to evaluate the effects of sowing date and intra rows spacing on yield, yield components and some phytochemical characteristics in Roselle, a field experiment was conducted as a split plot layout based on randomized complete block design with three replications in 2013 and 2014 growing seasons. Five sowing dates were considered as the main plots (11th and 30th of March, 14th of April, ...

In the visual cortex, many neurons respond preferentially to one direction of motion. Maps of direction preference vary in appearance between species and cortical areas. We propose that the observed variability in map appearance re/ect the variability in intra-cortical circuits as a consequence of wire length minimization. This hypothesis allows us to bypass a detailed developmental analysis of...

Grouping the machines and parts in a cellular manufacturing system based on similarities is known as the cell formation. This paper proposes a method for design of cell layout for a manufacturing system under dynamic demand environment for automation batch production industry. The proposed method of cell layout has two phases. In the first phase, Rank Order Clustering (ROC) was used to determin...
