For production using a Computer Numerical Control (CNC)-machining center, several process stages can be carried out on one machine with quick setup. The use of a single machine for all stages of the process certainly does not require transfer to the next machine. Thus, there are no material handling costs. However, the use of a single machine will result in longer batch waiting times as the production batch size increases. An increase in the batch waiting time will result in an increase in work-inprocess (WIP) inventory cost. This research was conducted to reduce the total variable cost consisting of WIP inventory cost and material handling cost. 2022-01-01T00:00:00Z http://hdl.handle.net/123456789/27891 Location determination with assigmnet method in design seaweed supply chain NU'MAN, A.

Currently, SWM causes problems not only in an environmental context but also in social and economic contexts. Therefore, integrated waste management (IWM) is an option that needs to be explored in municipal SWM . In this regard , it is necessary to develop models of an IWM system to integrate the formal system (government) with non-formal systems (informal sector/IS and community-based activity). To integrate all three groups’ roles in an integrated system , as theoretically there are 59 factors that influence IWM. However , not all factors are relevant to the implement ation in Bandung municipality because every city and country has different situation s and priority problems. For the case in Bandung municipality , based on studies , there are only 17 factors that influence IWM, i.e. waste generation, infrastructure, handled waste, reduction of waste, residual handling, final processing site, population/source of waste, mind-set and lifestyle, socialisation , recognition of IS, organisation of IS, clarity for the role of all stakeholders , accessibility of waste, quantity and quality of recyclable waste, price of recyclable material, waste picker income, and incentives or financial loans. 2018-08-01T00:00:00Z
