Factors for consideration in planning material flow


Many factors have to be taken into consideration for planning material flow in supply chain. In this article we are listing below each and every factor with necessary explanation wherever required. These factors will determine some of the characteristics of the flow pattern. All these factors must be taken into account before the actual task of designing a flow pattern. The factors are listed below:

a) Receipts: These pertain to inputs for production like raw materials, factory operating materials, packing materials etc.,
b) Shipments: These are mostly finished goods. The latest development is direct dispatches from plants on the basis of intranet communication from various distribution points.

2. Volume of production.

3. Number of different parts including Spares required for machinery in the plant and also for the spare parts market required for finished products of the company.

4. Number of operators: A HR specialist may be required here for categorization of various jobs and determining the number.

5.

In conclusion the committee of specialists appointed by the firm may adopt a 10 or 100 point scale and ascertain importance (like 3 highest, 2 medium, 1 least) to each attribute work out the score before taking a final decision on each factor. The specialists must include from each and every functional area.
