Selected Problems of Management of the Supply Subsystem in the Enterprise of the Foundry Sector: Determination of the Purchasing Sources and the Levels of Unit Material Consumption

The paper characterizes the tasks of the selected logistic subsystem in the area of the enterprise operations. The main aim of the study is to identify and analyse two tasks of management of the supply subsystem in the Enterprise X operating in the foundry sector. Firstly, planned sources of purchasing in the Enterprise X for the proposed redesigned manual meat mincer were determined.

The content of these processes can be determined by the reply to the most important questions connected with enterprise's core activities, concerning in particular make-or-buy decisions, which are connected with determination of the scope of permanent cooperative relationships. Next, the level of unit material consumption for manufacturing of cast products was evaluated for the proposed redesigned manual meat mincer. Effective operations of the Enterprise X depend on the effective meeting material needs for the internal production, auxiliary components for manufacturing of cast products and moulding materials which were estimated and presented in this study. The paper is based on the two items of the literature and author's own examinations conducted using the method of interviews with employees and customers in the Enterprise X.
