Lot sizing problem in production planning aims to optimize production costs (processing, setup and holding cost) by fulfilling demand and resources capacity costraint. The Capacitated Lot sizing Problem (CLSP) model aims to balance the setup costs and inventory costs to obtain optimal total costs. The object of this study was a plastic component manufacturing company. This study use CLSP model, considering process costs, holding costs and setup costs, by calculating product cycle and setup time. The constraint of this model is the production time capacity and the storage capacity of the finished product. CLSP can reduce the total production cost by 4.05% and can reduce setup time by 46.75%.  Keyword: Lot size, CLSP, Total production cost.

Throughout U.S. history, the production of difference, whether along racial or disability lines, has been inextricably tied to the imperatives of labor economy. From the plantations of the antebellum era through the assembly lines and trenches of early-twentieth-century America, ideologies of race and disability have delineated which peoples could do which kinds of work. The ideologies and identities of race, work, and the “fit” ’ or “unfit” body informed Progressive Era labor economies. Here the processes of racializing or disabling certain bodies are charted from turn-of-the-century actuarial science, which monetized blacks as a degenerate, dying race, through the standardized physical and mental testing and rehabilitation methods developed by the U.S. army during World War I. Efforts to quantify, poke, prod, or mend black bodies reshaped contemporary understandings of labor, race, the state, and the working body.

This paper discusses a digital twin-based approach for designing and redesigning flexible assembly systems. The digital twin allows modeling the parameters of the production system at different levels including assembly process, production station, and line level. The approach allows dynamically updating the digital twin in runtime, synthesizing data from multiple 2D–3D sensors in order to have up-to-date information about the actual production process. The model integrates both geometrical information and semantics. The model is used in combination with an artificial intelligence logic in order to derive alternative configurations of the production system. The overall approach is discussed with the help of a case study coming from the automotive industry. The case study introduces a production system integrating humans and autonomous mobile dual arm workers.
