“…The ε-constraint method has several advantages including the ability to generate different efficient solutions from various parts of the solution space as well, no need for scaling the objective functions, and simplicity. Its shortcomings include the efficiency of the optimal solution obtained is not guaranteed and the ranges of the objective functions should be specified in order to generate the grid points that will act as RHS (Nosoohi, Hejazi 2011).…”

The increasing population in large cities and the unbalanced urban growth associated with massive use of private cars in metropolitan areas often lead to traffic jams and road congestion that warrant the construction of such capital-intensive buildings as off-street public parking facilities. However, the initial problem in such projects is locating a suitable spot where all citizens can be conveniently served and the traffic load in busy city centers can be reduced by removing the need for on-street parking facilities. In this paper, an urban transportation network including, a number of parking demand points, a set of possible sitting locations, and several entry points of traffic flow are considered. Four objectives are generally considered for the public off-street parking location problem that include reducing traffic congestion, maximizing coverage demand, minimizing walking distance between demand points and new parking facilities, and decreasing related costs. The flow-capturing model has been exploited to develop two approaches for minimizing traffic congestion. Based on these approaches and other objectives, two models have been proposed. The covering distance of parking facilities will be uncertain in these models. Traffic flow entry points, driver’s path, and different types of parking lots have also been considered. Finally, relevant information and data required for implementing the proposed models were collected on two traffic zones in Central Business Districts (CBD) of Isfahan (Iran). Then, the ε-constraint method was used to solve the proposed multi-objectives models and the best candidate points for establishing new off-street parking facilities were determined.

“…The intent of preventive maintenance is to improve on one or more criteria, such as the maintenance cost, reliability, and availability. On the other hand, corrective maintenance refers to maintenance activities that are performed after the system has experienced a breakdown (Nosoohi & Hejazi, 2011). Usually, all maintenance activities, both corrective and preventive, are performed internally by an internal maintenance department.…”

Outsourcing is delegating partial or total business functions to other companies in conjunction with administrative and operational activities. One of the industries that implements outsourcing in its maintenance activity is the healthcare industry. An Intensive Care Unit (ICU) is part of a hospital which is very vital, so that it requires medical equipment with high availability and reliability. The aim of this research is to develop a performance model to use to assess the performance of medical equipment or the used maintenance outsourcing service providers. Developing the performance model involves 14 criteria. The 14 criteria were clustered by the Kano Model to obtain the importance of each criteria. . Kano was used to identify the criteria within the dimension of basic requirements and special requirements. DEMATEL was employed to identify the connection between criteria and ANP in order to provide the integrity of the criteria. The three criteria with the highest integrity rating were the technicians' capability by the rate of integrity that reached 0.256881, the aptitude of providing diagnosis by the rate of integrity that reached 0.222181, and the flexibility by the rate of integrity that reached 0.175684. Two criteria which had a rate of integrity of 0 and were considered as therefore having the lowest integrity rate were the criteria of charges and dependability respectively.

“…Maintenance activities can be categorised into corrective and preventive. The term corrective maintenance refers to activities that are performed after a system breakdown (Nosoohi & Hejazi, 2011). On the other hand, preventive maintenance, includes inspection and spare part replacement, and is performed before system breakdown.…”

Usually, maintenance activities are carried out by the maintenance department in a company, but now, some companies are outsourcing their maintenance activities. Outsourcing is the delegation of business functions to another company. The advantages of outsourcing include enabling a company to focus on its core business by outsourcing support activities, and changing fixed costs to variable costs. The aim of this research is to develop a multi-criteria performance measurement to assess the performance of maintenance outsourcing providers. Several previous studies have identified suitable performance criteria for maintenance outsourcing providers. However, those studies did not classify the criteria for achieving the desired level of performance. To address these shortcomings, this research has classified the criteria based on the Kano criteria. The criteria are: basic, one-dimensional, indifferent, reverse, and attractive. A managed case study analysis was performed at five Class B private hospitals in East Java to better understand the criteria in terms of the needs of a real hospital maintenance department. Previous research studies focused on understanding the relationship between each criterion and the associated level of performance, whereas the current research has focused instead on the relationship links between the criteria and the weighting of each criterion using DEMATEL-ANP. The outcome of this study is a simple instrument that can be directly used to evaluate the performance of maintenance outsourcing providers.
