Content analysis of OR job advertisements to infer required skills / Sodhi, M. S. in Journal of the operational research society (JORS), Vol. 61 N° 9 (Septembre 2010)

The method entailed collecting more than a thousand job ads from online sources, creating a hierarchy of sets of OR-related words and phrases, and then analysing the job ads using content analysis software to count the numbers of ads using the hierarchy of words and phrases. The method is particularly well suited for the periodic analysis of job ads to understand changes and trends, and is replicable in that, when carried out using our proposed keywords, it would yield the same results for any set of OR job ads.

Planning federal public investment in Mexico using multiobjective decision making / B. Cobacho in Journal of the operational research society (JORS), Vol. 61 N° 9 (Septembre 2010)

For this aim, we will analyse the problem in all its aspects: building the model from data using econometrical tools, solving the resulting highly complex model using modern efficient techniques (multiobjective meta-heuristics) and helping the decision maker to introduce his preferences in order to achieve the most preferred solution. This holistic approach let us provide an efficient solution to a complex public investment planning situation, improving the current state of the country relating not only economical aspects, but also social and human development aspects. The real situation studied is focused on Mexico, where, in recent decades, has undergone remarkable improvements in terms of economic growth, which has not been matched by significant improvements in several other basic aspects of human development, nor by reductions in regional inequalities. This suggests the need to establish policies aimed at improving these aspects and reducing inequalities. Federal public investment is an important tool in regional policy to promote and improve these aspects; so we introduce a multiobjective programming problem for planning federal public investment in Mexico. This model will focus on improving national levels in four main dimensions of human development (economic growth, education, health and housing), and on reducing regional inequalities for those dimensions.

An ant colony optimization metaheuristic for single-path multicommodity network flow problems / Li, X. Y. in Journal of the operational research society (JORS), Vol. 61 N° 9 (Septembre 2010)

We study two versions of this problem based on two different objectives. The first version is to minimize network congestion, an issue of concern in traffic grooming over wavelength division multiplexing (WDM), and in which there generally exists a commodity flow between every pair of nodes. The second problem is a constrained version of the general linear multicommodity flow problem, in which, for each commodity, a single path is allowed to send the required flow, and the objective is to determine a flow pattern that obeys the arc capacities and minimizes the total shipping cost. Based on the node-arc and the arc-chain representations, we first present two formulations. Owing to computational impracticality of exact algorithms for practical networks, we propose an ant colony optimization-(ACO) based metaheuristic to deal with SMNF. Considering different problem properties, we devise two versions of ACO metaheuristics to solve these two problems, respectively. The proposed algorithms’ efficiencies are experimentally investigated on some generated instances of SMNF. The test results demonstrate that the proposed ACO metaheuristics are computationally efficient and robust approaches for solving SMNF.

An analytic network process approach to the selection of logistics service providers for air cargo / Y. H. Yang in Journal of the operational research society (JORS), Vol. 61 N° 9 (Septembre 2010)

The logistics needs in a supply chain consist of many different interrelated services, each with its own set of requirements and constraints. A logistics agent might specialize in the provision of a single logistics service or might provide a range of services. The selection of logistics agent(s) cannot be separated into a series of stand-alone selections as the decisions are interrelated. Decision makers must assess the merits of individual activity-agent combinations, as well as their interrelationships along the entire supply chain. Such an evaluation is non-trivial, because both tangible and intangible elements are involved. In this research, we model the selection problem using analytic network process, a multiattribute decision-making methodology suitable for assessing interdependent elements, both tangible and intangible. We examine the significance of integration and consolidation of shipments, the trade-offs between costs, benefits and risks within activities of the logistics process, and the differing roles of traditional freight forwarders and integrators.

We suggest an explanatory model for the success of retailers that operate on the Internet. Non-financial information has been used to identify several intangible constructs: ‘web traffic generation’, ‘relevance in search engines’, ‘link popularity’, and ‘blogs popularity’. The success is measured through items derived from financial statements: sales and profits. The model has been built within a structural modelling framework. It has been estimated using Partial Least Squares with a sample of USA e-tailers. The results show that there is a significant relationship between the intangible constructs and accounting figures. This relationship is stronger when we consider Sales from Internet Operations rather than Total Sales or Net Profit.

The first is the removal of any initialisation bias, the second is ensuring that enough output data is produced to obtain an accurate estimate of performance. This paper is concerned with the first issue, and more specifically warm-up estimation. Our aim is to produce an automated procedure, for inclusion into commercial simulation software, for estimating the length of warm-up and hence removing initialisation bias from simulation output data. This paper describes the extensive literature search that was carried out in order to find and assess the various existing warm-up methods, the process of short-listing and testing of candidate methods. In particular it details the extensive testing of the warm-up MSER-5 method.

Typically these problems include an upper planning-level optimization with some discrete decision variables (eg, build/don’t build) as well as a lower operations-level problem often described by an optimization or nonlinear complementarity problem. This lower-level problem may also include some discrete variables. MPECs are very challenging problems to solve and the inclusion of integrality constraints makes this class of problems even more computationally difficult. We develop a new variant of the Benders algorithm combined with a heuristic procedure that decomposes the domain of the upper-level discrete variables to solve the resulting DC-MPECs. We provide convergence theory as well as a number of numerical examples, some derived from energy applications, to validate the new method. It should be noted that the convergence theory applies if the heuristic procedure correctly identifies a decomposition of the domain so that the lower-level problem's optimal value function is convex. This is challenging but our numerical results are positive.
