this paper presents a new mathematical model for a bi-objective job shop scheduling problem with sequence-dependent setup times that minimizes the weighted mean completion time and the weighted mean tardiness time. for solving this multi-objective model, we develop a fuzzy multi-objective linear programming (fmolp) model. in this problem, a proposed fmolp method is applied with respect to the o...

the purpose of this article is to present a model for customer satisfaction in the development banking sector. in the design of the customer satisfaction model, an attempt has been made to consider the characteristics of the development banks. thus, three dimensions of quality of service, characteristics of the service, and access to service have been considered as the main dimensions of the mo...

background : despite many progresses in the improvement of care status and the management of acute coronary syndrome, cares quality is far from the desirable conditions. today, due to the great emphasis on resources management, costs control, the effectiveness of patient care, improving quality and responsibility, the good patient care is necessary. two dimensions are referred for improving the...

price fairness and price satisfaction is one the most important fields in pricing and also in customer satisfaction. in this research, first the dimensions of price fairness, price satisfaction, customer satisfaction, and customer loyalty are extracted from marketing literature, then five hypotheses are developed. in proposed model, price fairness has direct impact on price satisfaction, custom...

We present a constraint-based approach to interactive product configuration. Our configurator tool FdConfig is based on feature models for the representation of the product domain. Such models can be directly mapped into constraint satisfaction problems and dealt with by appropriate constraint solvers. During the interactive configuration process the user generates new constraints as a result o...

We study threshold properties of random constraint satisfaction problems under a probabilistic model due to Molloy [11]. We give a sufficient condition for the existence of a sharp threshold that leads (for boolean constraints) to a necessary and sufficient for the existence of a sharp threshold in the case where constraint templates are applied with equal probability, solving thus an open prob...

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...

one of the most important factors that affects on job producitivity refers to personnel. motivation and job satisfaction (j.s) explain the reason and cause of human behavior in organization. then the study of this topic will be very important. in this paper causal model of efficient factors of job satisfaction developed by path analysis model. in this paper path analysis model have explained di...

In this paper we deal with the problem of identifying a valid way to characterize heterogeneity in the analysis of customer satisfaction observing the phenomenon through a new perspective. In the literature, the variability of a Customer Satisfaction index is measured by the standard deviation or the coefficient of variation. In this way, heterogeneity among customers may be masked. To overcome...

The constraint satisfaction problem (CSP) and its quantified extensions, whether without (QCSP) or with disjunction (QCSP∨), correspond naturally to the model checking problem for three increasingly stronger fragments of positive first-order logic. Their complexity is often studied when parameterised by a fixed model, the so-called template. It is a natural question to ask when two templates ar...
