“…Further, the matrices , , , and can be converted into the 2-tuple fuzzy linguistic form. On this basis, by (1) and (3), the weights and the performance evaluation values of each expert with respect to each index in the dimension IIES can be obtained; i.e., the weights are Finally, by (4) and (6), we can obtain the comprehensive evaluation value of enterprise A the expert group, i.e., ( , ) = (M, 0.29) and ( , ) = (M, −0.13), which is shown as the point P in region II in Figure 4. The point P shows that the importance of logistics to enterprise success A is higher, but the enterprise operation logistics capacity is lower.…”

“…The management performance is an important index for the operation level of the enterprise [1,2]. In many related influence factors of the enterprise management performance, the logistics operation mode is an important factor which cannot be ignored [3]. It plays an important role in improving the enterprise management performance [4][5][6].…”

The right choice of logistics operation mode is not only the foundation for improving the comprehensive operation level of an enterprise, but also an important way to improve the management performance. Nevertheless, the study on this aspect is still lacking. In this paper, we develop a novel method for selecting enterprise’s logistics operation mode. First, we give the analysis of main types and characteristics of the logistics operation modes. According to the two dimensions of the Ballou model, i.e., the importance of logistics to enterprise success and the enterprise operation logistics capacity, we set up an evaluation index system for selecting enterprise’s logistics operation mode through literature analysis. Then, the each index is evaluated using the fuzzy language assessment method, and evaluation value of each index in the two dimensions is calculated using the 2-tuple fuzzy linguistic representation model. Furthermore, a two-dimensional matrix model for selecting enterprise’s logistics operation mode selection is built. According to the model, the right logistics operation mode can be selected. Finally, an example is used to illustrate the practicality and validity of proposed method.

“…Besides the integrated approach toward developing decisions in the distributive logistics is often connected with the previous business processes in the supply chain (purchasing, transportation, production). In particular, such an approach has been suggested by Safaei et al (2018). The scientists have developed the optimization model for the network "supply-distribution" under the conditions of undetermined parameters of demand and supply.…”

Integrated decisions in the system of the marketing logistics are the main resource for providing the efficient management of the value chain. Moreover, there is not a sufficient number of methodological approaches, which could use in complex the principles of the integrated modelling of decisions in the operational systems “procurement marketing – supply logistics” and “sales marketing – distribution logistics”. Considering that fact, the methodology of selecting strategic alternatives based on the integrated modeling in separate marketing logistics chains and in stage-by-stage formation of the supply chain participants has been developed in the article. The research is based on the application of the AHP method and the method of planning “dual sourcing” (70/30) for grounding the selection of the supply strategy at the market of material resources; methods of optimal planning according to Bayes criterion, linear programming and logistics modelling – for grounding the selection of the managerial decisions on the strategy of distributing the ready produce. The research covers, firstly, grounding the essence of the marketing logistics through the systemic approach to identification of its main and servicing business processes; secondly, improvement in the process of planning decisions in the procurement marketing system by adding the procedure of the logistical selection of the hierarchical estimation with a different degree of advantages in alternative supply strategies; thirdly, formation of the cascade integrated approach toward selection of the alternative distribution channels for the finished produce by estimating the complex marketing effect and application of the logistical model of optimal distribution.

“…Mathematically, in a multi-level programming problem, constraints contain a sequence of parametric optimization problems, which should be solved in a predetermined order, and higher level variables are considered as parameters in the lower level programming problems. Multi-level programming problems have many applications in various situations such as those in supply chain management [1,2], network defense [3,4], planning [5], logistics [6] and economics [7]. Although most of the research concerning multi-level programming has focused on the cases that include only two levels (referred to as bilevel programming) [8,9], there are many multi-level programming problems that involve more than two levels.…”

In this paper, we consider a general version of a linear trilevel programming problem. Three different types of optimistic optimal solutions for a special trilevel programming problem have formerly been suggested. This paper presents the mathematical formulation of all of the three types of optimistic optimal solutions for the given linear trilevel programming problem. Moreover, some properties of the inducible region (the feasible region for the trilevel programming problem) corresponding to each optimistic optimal solution are investigated. Finally, a numerical example is presented to compare the different types of optimistic optimal solutions.
