Abstract
There are myriad sources of variation in our experiments, including raw materials, process conditions and parameters, adjustments made by operators, measurement systems and customer use. We focus here on the latter, considering three different scenarios. For each scenario, we describe the problem and ask: How should we choose factors, factor levels and response variables in our experiments? What information do we need in order to make these choices? How do we obtain this information?
Common to all three scenarios is the nature of the product. It is used by the customer with either a variety of their own products, or under varying conditions, or both. For example, our printer is used by the customer to print a variety of fabrics with a variety of inks; our packaging system is used by the customer to pack different types of produce at varying conditions of temperature and humidity, and then stored under different conditions; our plastic agricultural product is used in a variety of fields or orchards, etc. Note that conditions of use include both random and fixed effects, for example, in the case of the ink or the produce, there are both types and batches of ink and produce.
Scenario 1: The product/process has been developed. We aim to characterize the conditions of use e.g. define “our product works at temperatures below 40C”, “our system can be used to package the following types of produce…”
Scenario 2: A completely new product/process is being developed. We aim to both enable it to work with a wide range of conditions of use and to characterize the conditions of use.
Scenario 3: We have a range of existing products/processes, with available field data from beta testing, complaints, and service records. A new product/process, similar to existing ones, is being developed. We aim to both enable it to work with a wide range of conditions of use and to characterize the conditions of use.
This talk includes an opportunity for conference participants to discuss the issues raised.
