SPARES OPTIMIZATION

Objectives

The aim of this course is to give the participants an understanding of the field of spares provisioning and spare parts optimization. Special focus is placed on the mathematical models and the theory that form the foundation of this field.

Course Structure

Initially, we give a general introduction to mathematical modeling, decision making and optimization. With this general understanding in hand, we concentrate on the design of support systems and especially the sparing strategies within the support system. Standard theories and assumptions are motivated and justified. The course participants are guided through the model evolution from the seminal METRIC / OPUS1 models through improved approximations (Vari-METRIC / OPUS8) to modern models handling, e.g., discardables, partially repairable items and scheduled removals.

A common theme is to seek to strengthen the participants understanding by offering exercises on central topics:

introduction to mathematical modeling and optimization
introduction to support systems and support system design
building a mathematical model for multi-echelon repairable item inventory systems

                      - METRIC / OPUS1
                      - input data requirements
                      - assumptions (the Poisson process, Palm’s theorem)
                      - forming and retrieving effectiveness measures from the model
                      - multi-indenture (material breakdown structure)

spare parts optimization

using engineering judgment

using single item – single site modeling

using the systems approach

exercise 1: illustration of the differences between 1, 2, and 3 and the improvements obtained
key optimization technique 1 – marginal allocation
exercise 2: build your own multi-item, single-indenture, single-site optimizer in Excel
improved approximations

                      - the exact model
                      - the negative-binomial approximation
                      - batched demand

key optimization technique 2 – convexification
