Planning of warehouse area for vise manufacturing by considering raw material requirements

Availability of raw materials is important for maintaining the continuity of production. However, in planning inventory for raw materials, several factors such as availability of warehouse space for raw material, handling cost, order cost, transportation time are used in determining amount of raw material need to be stocked. Vise is important tool to support finishing process such as cutting and grinding. Vise consists of several parts such as base, right clamp body and handle. These parts need to be stored in warehouse to support the manufacturing of vise. Hence, the warehouse space must be adequate to store raw materials for manufacturing vise within certain period of time. This paper aims to demonstrate the calculation of warehouse area based on the material requirements that are calculated based on material removal rate for each process.
