Optimal Processes Management for Over-Adjusted Process with Dependent Steps on Bank Industry

摘要

Process management is important for a company. An over-adjusted process may increase process quality variability, ultimately affecting the quality and cost of service or products. A two special-cause economic over-adjustment model is developed for controlling the service quality variation of the two-step process on a bank industry. The objective is to determine the optimal management policy for the two-step process, which minimizes the service quality variation and total quality control cost. A Markov chain approach is extended to derive the economi c adjustment model of the process, and the optimal management policy is obtained from optimization techniques. Application of the two special-cause over-adjusted model and the optimal management policy on the process management of a bank industry is demonstrated through an example.
