Quality, class, and competition

Article Abstract:

A formal economic model for quality management is presented. This framework combines the process-oriented perspective of quality in manufacturing and the multi-attribute product positioning and customer preference models of marketing. To integrate both views, a product is defined by a vector of performance attributes and the population of produced units is described to demonstrate a distribution on these attributes. This model uses the characterization of a product as an aggregate of attributes, which is based on the popular paper by Lancaster (1966). The traditional model is expanded by describing firms that manufacture and market a population of products with a probability distribution on product attributes.

Batching to minimize flow times on one machine

Article Abstract:

Solutions are developed for two kinds of minimum flow-time sequencing problems with lot-sizing. An index rule for ordering items is given to solve an 'item-flow' problem. The single-product, 'batch-flow' problem is solved by processing unequal batches that are ordered in decreasing size.
