Data Envelopment Analysis (DEA) is one of the most popular techniques for measuring the relative efficiencies of a set of decision making units (DMUs), which use different inputs producing various outputs. Ranking of efficient DMUs is one of the most interesting DEA perspectives. However, there are cases where we see some limitations on available resources and the proposed model of this paper is associated with Indicator with Limited Sources (ILS), which affects ranking methods. The ILS exists as fixed amount in a community and the DMUs can own it with their abilities. When a DMU loses the same amount of the indicator, the rest of the DMUs are able to own some without even changing their capacities of other indicators and or vice versa. If a DMU looks for more of the same amount of the indicator, the rest of the DMUs have to supply it without even changing their capacity of other indicators. This paper develops a ranking method based on the ILS for the efficient DMUs, when there is changes either in inputs/ outputs ILS. The implementation of the proposed model is applied for a case study of banking system.

Activity-based costing (ABC) is a method, which identifies activities in a firm and assigns the expenses of each activity with resources to all products and services based on the real consumption by each. This method allocates more overhead costs into direct expenses compared with conventional method. ABC method is normally used for costing as well as monitoring different activities, which involves tracing resource consumption. This paper presents a survey on advances of ABC based method. The study has discussed the advantages and disadvantages of the implementation of ABC based method in different industries. The survey also discusses recent advances on time driven ABC method in health care industries.

A microwave-assisted method was developed for the synthesis of aldol adducts using RuCl3.nH2O-BINAP as an efficient catalyst. Important advantages of this technology include environmentally benign condition, highly accelerated rate of the reaction with an improvement in the chemoselectivity and quality of the products.

A new analytical approach was proposed to monitor the reaction between epoxidized soybean oil and diethylene glycol in the presence of ZnCl2 as an epoxide ring opening catalyst for microwave assisted synthesis of polyol. Infrared spectra of the products were used as the input data, being processed by multivariate curve resolution – alternating least squares (MCR-ALS) for quantitative monitoring. The data obtained in different MW powers were analyzed by MCR factor analysis coupled with ALS optimization procedure. Standard deviation of residuals for experimental data and the variance explained at the optimum condition (r2) were 0.135 and 97.24% respectively.

During the past two decades, there has been a growing concern on environmental issues around the world. Firms try to provide better production plans to recycle their used materials to reduce pollution from environment. In fact, lack of management in municipal solid waste for methods of collecting, disposal and processing of them can be significant damage to the environment, This paper presents a mathematical model for pet waste management, which plays essential role on municipal solid waste. The modeling formulation is a nonlinear probable mathematical programming model for chemical recycling the PET waste. In this model, the optimal amount of waste is determined by considering collected operations of reverse logistics and chemical recycling when demand is under uncertainty.

During the past few decades, many organizations have attempted to increase their productivity
through outsourcing parts of their responsibilities. Outsourcing helps firms reduce their low
value added activities and focus on their high value added activities. It also helps organization
save their time and energy which leads to more efficient units. The idea of outsourcing is more
important for project based organizations where the nature of works is different from a
particular project to another one. This paper presents an integrated balanced score card system
with an adaptation of ELECTRE III method to select suitable resources for outsourcing. The
proposed model of the paper is implemented for a case study of subway system in Iran and the
results are discussed.

One of the primary concerns on supply chain management is to select appropriate suppliers based on different criteria, which are often in serious conflict. In this paper, we present a fuzzy TOPSIS technique to prioritize suppliers on reverse logistic network based on different criteria and then the proposed model of this paper applies fuzzy linear programming technique to determine optimum order quantity associated with each supplier. There are three criteria associated with each supplier including technical skills, equipment and ability to analyze. The implementation of the proposed method has been demonstrated in case study.

In this paper, a bi-objective mathematical model for emergency services location-allocation
problem on a tree network considering maximum distance constraint is presented. The first
objective function called centdian is a weighted mean of a minisum and a minimax criterion
and the second one is a maximal covering criterion. For the solution of the bi-objective
optimization problem, the problem is split in two sub problems: the selection of the best set of
locations, and a demand assignment problem to evaluate each selection of locations. We
propose a heuristic algorithm to characterize the efficient location point set on the network.
Finally, some numerical examples are presented to illustrate the effectiveness of the proposed
algorithm.

The economic lot scheduling problem (ELSP) is a challenge between sequencing and lot sizing. In this problem, several products must be produced on a single machine in a cyclical production pattern and the primary goal is to minimize the total setup and holding expenditures. Since time affects the value of money, it is necessary to take into account the time value of money when gradual payment is the case. In this paper, a new ELSP model with the consideration of the time value of money is considered. The proposed model of this paper is formulated as a nonlinear mixed integer model and a hybrid GA is presented to solve the resulted model for large-scale problems. The proposed method is solved for some benchmark problems for large-scale problems.

One of the most important issues on quality of building structure is its resistance against
earthquake. Earthquake, as one of natural disasters, has been one of the main reasons of fatal
incidents in developing countries. Any attempt to increase the quality of building structure
could reduce any possible damages an earthquake could cause on society. This paper presents a
system dynamic model to study the importance and behavior of the factors which affect the
construction quality of buildings & apos; structures. The proposed model of this paper is analyzed for a
case study and the results are discussed. The paper also uses DEMATEL technique to compare
the results of the proposed method. The paper concludes that among the whole factors which
affect the construction quality of buildings & apos; structures, the "performance of related
organizations and institutions" is of the most important ones.
