On Various Controlling Issues in Production and Inventory Planning and Scheduling (PIPS): an Operations Management Viewpoint
In this presentation the author provides his perspective on important controlling issues in production and inventory planning and scheduling. Drawing on his experiences as Materials Manager and as Apparel Research Center Research Director, the author provides his thoughts on important issues in the justification of advanced technology and how to evaluate such investments. Key measures of performance in PIP are described and several key relationships among them are provided. The author concludes with a challenge for students of controlling to adopt more proactively the concept of mapping cash flows and applying the NPV concept for decision making and performance measurement in production.

Toward “Controlling” the Planning of Operations: The Classifying of Planned Inventory
Existing inventory classification approaches/schema in manufacturing help answer question such as “What inventory do we have?” What stage is it in?” ”How is it to be valued?” But another line of questions is also very important: “What inventory are we planning to have?” and “Why are we planning to have it?” Such is the motivation here: to develop a scheme for the classification of planned inventory. So in a sense here the emphasis is on the control of the planning process. Is planning being done well? To this end we introduce a time-phased classification of planned inventory by motive.

Time Phasing Safety Stocks for Production Planning
Safety stocks are commonly used in inventory management for tactically planning against uncertainty in demand and/or supply. The common approach is to plan a single safety stock value for the entire planning horizon. We introduce a new line of research in inventory management: the notion of time phasing safety stocks. We assert that time phasing of safety stocks over the planning horizon makes sense because larger safety stocks are appropriate in times of greater uncertainty while lower safety stocks are more appropriate when demand and/or supply are more predictable. We demonstrate that significant savings that can be achieved by time phasing safety stocks and provide a simple procedure for incorporating them into production planning systems that minimizes safety inventory. We then illustrate a planning system feature, which supports decision making in production planning by showing the inventory implications of safety stock plans.
