The manufacturing cell design problem aims at organizing a manufacturing plant in cells that contain machines processing parts from a same family for a given product. The purpose is to minimize the flow of parts among cells so as to increase productivity while reducing costs. This paper focuses on comparing metaheuristics and constraint programming –from a modeling standpoint– when used to solv...

Introduction As time-to-market pressures increase, design engineers continually look for ways to advance the development of system-level products and ensure problem-free manufacturing. Programmable logic devices (PLDs) that support in-system programmability (ISP) can help accelerate development time, simplify manufacturing flow, lower inventory costs, and improve printed circuit board (PCB) tes...

aims: musculoskeletal disorders are common occupational hazards and disabilities in developing countries. this study was to assess postures and determine musculoskeletal disorders in employees of a water flow meter manufacturing factory in iran. materials & methods: in this descriptive analytical study that was done among workers of iran ensheab factory from water-counter manufacturing industry...

In-circuit testers are widely used for manufacturing tests and for the measurement of printed circuit board (PCB) systems. In-circuit testers can also program and verify programmable logic devices (PLDs) that support in-system programmability (ISP). Using in-circuit testers to program ISP-capable devices allows device programming to fit into the standard manufacturing flow, reducing time-to-mar...

There is a manufacturing system where several parts are processed through machining workstations and later assembled to form final products. In the event of disruptions such as machine failure, original flow-shop schedule needs be revised and/or rescheduled. scenario, rescheduling methods based on right-shift affected operations work very well. Here in this study, deviation make-span from used ...

Este estudo tem como objetivo analisar o fluxo de material da fabricação pás turbina eólica para um parque eólico onshore com capacidade nominal 300 Megawatts (MW). Para tal, foi utilizado método Análise Fluxo Material (AFM) no software STAN® 2.7.101. Foi estimada uma demanda 4,946 t e geração 514 resíduos compósito fibra vidro resina epóxi na 225 em ano. Desta forma, práticas produção mais lim...

Assembly lines are special kinds of production systems which are of great importance in the industrial production of high quantity commodities. In many practical manufacturing systems, configuration of assembly lines is fixed and designing a new line may be incurred huge amount of costs and thereby it is not desirable for practitioners. When some changes related to market demand occur, it is wo...

INTRODUCTION Since the early 1990s, recombinant human clotting factor VIII (rhFVIII) produced in hamster cells has been available for haemophilia A treatment. However, the post-translational modifications of these proteins are not identical to those of native human FVIII, which may lead to immunogenic reactions and the development of inhibitors against rhFVIII. For the first time, rhFVIII produ...
