Three cell loading and job scheduling strategies are proposed and tested with two newly developed mixed integer programming models. Additionally, three types of due dates (tight, medium and loose) and three different demand levels were considered. Finally, two tardy job assignment methods were proposed to observe the impact on nT. Case problems were solved based on minimising nT, Tmax and total tardiness (TT) objectives and cost sensitivity analysis was performed. Results indicated that, the first strategy, (early start allowance and tardy job assignment after each period) performed better in terms of nT. For the secondary objectives, tradeoffs were observed among different strategies depending on the type of due date, demand level and tardy job assignment method.","PeriodicalId":191561,"journal":{"name":"Int.

To address this challenge, this paper first suggests a three–layer framework for strategic supplier relationship portfolio management. It then proposes a fuzzy binomial tree approximation–based stochastic model to analyse relationship dynamics and the value of a supplier relationship portfolio, taking into account both randomness and fuzziness uncertainty. Furthermore, it develops a decision model for supplier relationship portfolio configuration and adaptive development planning. Numerical examples are provided and some managerial implications are discussed.","PeriodicalId":191561,"journal":{"name":"Int. J. Adv. Oper.

One of questionnaire was based on analytical hierarchical process (AHP) methodology. These factors were discovered with the help of literature survey and then AHP method with fuzzy was applied for prioritising. Our research provides the direction to the managers who are involved in telecom operation, how can they judge their telecom service quality and improvement thereof to retain their prospective customers.

The results are some new products with more utility for both the buyer and the producer. The methodology proposed to determine value adding functionalities for convergent products. A collection of base functions and sub–functions configure the nodes of a web–based (digital) network representing functionalities. Each arc in the network is to be assigned as the link between two nodes. The aim is to find an optimal tree of functionalities in the network adding value to the product in the web environment. First, a purification process is performed in the product network to assign the links among bases and sub–functions. Then, numerical values as benefits and costs are determined for arcs and nodes, respectively, using a mathematical approach. A heuristic zero/one programming is developed to provide a solution framework. Finally, the Steiner tree methodology is adapted to a bi–objective model for the network to find the optimal tree determining the value adding sub–functions to bases in a convergent product. An example is worked out to illustrate the applicability of the proposed approach.","PeriodicalId":191561,"journal":{"name":"Int. J. Adv. Oper.

Selecting a location for a new organisation or expansion of an existing one is a crucial decision for its eventual success or failure. This paper presents a fuzzy multi-criteria decision-making (MCDM) method based on axiomatic design principles for solving facility location selection problems under group decision-making environment. The group of decision makers is assumed to be homogeneous where the degrees of importance (reliability) of all decision makers are taken to be equal to each other. The decision of selecting an appropriate facility location for a distribution centre, manufacturing set-up, commercial complex or any public organisation always involves consideration of many socio-economic criteria which can be more effectively expressed in qualitative terms. Trapezoidal fuzzy numbers are used here for representing those qualitative criteria into quantitative values. The location alternatives are ranked based on the ascending values of their total information content. Two illustrative examples are solved applying the adopted method to validate its universal applicability and acceptability as an almost accurate and comprehensive MCDM tool. A sensitivity analysis study is also performed.","PeriodicalId":191561,"journal":{"name":"Int. J. Adv. Oper.

It operates in various types of culture and each year has led to major losses to farmers across the nation. To combat the whitefly, pesticides or agrochemicals increasingly powerful are being used. One consequence is the contamination of soils, rivers and also risks to consumer health, particularly crops of tomatoes, cucumbers, strawberries, beans and many others. One way to combat the whitefly is to find ways to combat these pests when the attack is at the beginning. For this purpose, an information system will be built in order to detect the growth of this plague and also give conclusions about the behaviour of this plague in different environments and culture (rice, bean, cucumber, corn and so on). With the system identifying the growth of the plague and also how to spread, then it is possible to combat the plague before it spreads. Thus, fewer pesticides are inserted into the soil and indirectly into the rivers. Thus, it also allows the reduction of costs fighting this plague and also reduce production losses. This paper describes this information system and also the technology involved.","PeriodicalId":191561,"journal":{"name":"Int. J. Adv. Oper.

Currently, it is increasingly common for the creation of technical barriers to prevent access of products to markets.

The Brazilian model, as well as the European, adopted for the conformity assessment, the methodologies and theoretical principles of enshrined in international normative documents. The backbone of the Brazilian does not differ much from the European model. The technical and conceptual bases of the Brazilian system, as well as in the European system, are those established and practiced internationally. The differences lie mainly in the implementation.

The high-runner products are handled using a kanban system and low-runner products using a base stock system. The PKB systems were differentiated in terms of the model driver, loading rule, and rework entrance policy. The performance measures adopted the total output, average work-in-process, flow times and average machine utilisations. Discrete-event simulations were conducted with an analysis constituted of multi-factor ANOVA and response surface methodology. From the analysis, there is a specific R(LR) value that gives desired performance, and at the same time, its dependency is solely on accuracy of regression equation. Between rework policies, predominantly merge rework entrance policy yields more desirable results as observed within performance measures, compared to original rework entrance policy.","PeriodicalId":191561,"journal":{"name":"Int.

Although this area has only recently begun to be investigated, a number of important reports have been published, in which these substances have been shown to cause significant abnormalities in the endocrine system of animals, thereby directly affecting the environment and natural cycles. These emerging contaminants are generally pharmaceutical products that are used for personal hygiene, natural hormones, illicit drugs, industrial by-products and indicators of anthropogenic activity. The methodology adopted involved filtering samples with glass fibre and cellulose acetate membrane filters, extraction and concentration using the solid phase extraction (SPE) method, and analysis using potentiometric detectors incorporated in a continuous flow system.
