Abstract Evolutionary algorithms have proven to be very successful in solving multi-objective optimization problems (MOPs). However, their performance often deteriorates when constraints are introduced. This paper proposes a hybrid heuristic intelligence (HHI) approach remedy this issue. First, classification operator is designed sort individuals by relative constraint values, which enlarges th...

The final quality and cost of a manufactured product are determined to a large extent by the engineering design of the product and its production process through activities of off-line quality control methods, namely, System Design, Parameter Design and Tolerance Design. However, in the context of most non-industrialized countries, the off-line quality activities of product design and system de...

Brief No. 1 referred to the trend of Australian State and Territory child protection systems to shift the balance from a ‘forensic’ investigation of suspected child maltreatment to one where a greater emphasis was placed on family support and the promotion of a ‘needs’ approach to the management of suspected child maltreatment cases. As Tomison notes (1998a), much of this change in practice sys...

in many practical distribution networks, managers face significant uncertainties in demand, local price of building facilities, transportation cost, and macro and microeconomic parameters. this paper addresses design of distribution networks in a supply chain system which optimizes the performance of distribution networks subject to required service level. this service level, which is considere...

Introduction: Students are the main clients for an educational system. It is believed that using their viewpoints to determine the educational gap is of great value. This can also help to promote educational programs. The aim of this study was to evaluate educational service quality based on students’ points of view in Mashhad University of Medical Sciences (MUMS) in 2016. Method: In a cross-se...

When constructing or improving large complex systems, design activities help establish the needs and goals of users, deepen the understanding of the system and facilitate ideation of new solutions. When service systems are large, dynamic and complex, the need for thorough design work is especially evident. However, design methods usually strive to describe and design best case scenarios and we ...

Service discovery has been recognised as an important aspect in the development of service centric systems, i.e., software systems which deploy web services. To develop such systems, it is necessary to identify services that can be combined in order to fulfill the functionality and achieve quality criteria of the system being developed. In this paper, we present a framework supporting architect...

PhoneFactor is a token-less two-factor authentication service for user remote logons [13]. This allows users of an organization to be authenticated through an automated phone call to the user’s phone before access is allowed. In this paper, we present the service management architecture of PhoneFactor that depends on both the Internet and the public switched telephone network (PSTN), and we ide...

Service personalization has direct consequences on service perception and service evaluation. As number of mobile users continue to rise, researchers must focus on addressing the problem of inadequate service personalization due to lack of effective mobile service personalization system. This study underscores the importance of the need for an optimized design for the smartphone based web servi...
