The design of cellular manufacturing system (CMS) involves many structural and operational issues. One of the important CMS design steps is the formation of part families and machine cells which is called cell formation. In this paper, we propose an efficient algorithm to solve a new mathematical model for cell formation in cellular manufacturing systems based on cell utilization concept. The p...

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...

Current industrial silicon heterojunction (SHJ) modules use scarce materials such as silver for screen-printed contacts, indium indium-tin-oxide (ITO) transparent conductive oxide (TCO) layers, and bismuth Sn-Bi coated Cu wires low-temperature interconnection. SHJ solar cells more than double the (30.3 mg/W) mainstream passivated-emitter rear cell (PERC) technology. However, most pressing issue...

two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including mcf-7 (breast cancer cell), hepg2 (liver hepatocellular cells), a549 (adenocarcinomic human alveolar basal epithel...
