Customer Satisfaction Index (CSI) employs a model for measuring and quantifying the satisfaction of customers who have used particular products and services. CSI provides a uniform measure of customer satisfaction that allows for comparison across industries and it illustrates how customer satisfaction is embedded in a system of cause–effect relationships. Despite discussions of nonlinear relat...

PLS Path Modeling is a widely used approach in marketing. In that field, relationships between latent variables are frequently nonlinear. This nonlinearity is usually defined by a piecewise linear function. In this talk, we present an approach to include non linear transformations of the latent variables in the PLS path modeling algorithm with monotonic B-splines. We use optimal scaling methods...

This paper presents a multi-criteria vehicle routing problem with soft time windows (VRPSTW) to mini-mize fleet cost, routes cost, and violation of soft time windows penalty. In this case, the fleet is heterogene-ous. The VRPSTW consists of a number of constraints in which vehicles are allowed to serve customers out of the desirable time window by a penalty. It is assumed that this relaxation a...

in this paper an approach based on evolutionary algorithms to find pareto optimal pair of state and control for multi-objective optimal control problems (moocp)'s is introduced‎. ‎in this approach‎, ‎first a discretized form of the time-control space is considered and then‎, ‎a piecewise linear control and a piecewise linear trajectory are obtained from the discretized time-control space using ...

Hitoshi Matsushima Toshiyuki Sato Takashi Sato Toshiaki Koyama ABSTRACT: By the maturity of the economy and the increase of competition among enterprises, various customer channels, the quality of services, customer satisfaction, and productivity in offices are becoming increasingly important. Telephones and facsimiles are real-time communication devices which provide users with an interface po...

delivering perishable products to customers as soon as possible and with the minimum cost has been always a challenge for producers and has been emphasized over recent years due to the global market becoming more competitive. in this paper a multi-objective mix integer non-linear programming model is proposed to maximize both profits of a distributer and the total freshness of the several produ...

quality of products and services is considered as a key factor for customer satisfaction. quality function deployment (qfd) is known as a critical tool for translating voice of customers to prioritize technical requirements of a production. the level of this satisfaction depends on the number of fulfilled requirements. it should be noted that this level varies according to the possible constrai...

A considerable amount of research has been concerned with the domain of automatic planning and scheduling, but many real world scheduling problems such as The Pick up and Delivery Problem With Time Windows (PDPTW) are still not easily tackled. The PDPTW problem demands solving the schedule for each vehicle of a transportation fleet where pick up and delivery of customer orders are distributed a...
