Abstract: Our research focuses on the development of two algorithms based on the mathematical programming and local search procedures for resolution the Multi-Item Capacitated Lot Sizing Problem and Vehicle Routing Problem (MICLSP-VRP). It concerns so a particularly important and difficult problem in the strong sense for solving. In particular, our study is motivated by a real case study in a butcher’s shop firm whose meat processing. Several production lines are considered of (turkey and chicken) items and a fleet of vehicles that is used to deliver. In this study, an effective approach based on the local search and accurate mixed integer programming model is presented to solve multi-item capacitated lot sizing problem and vehicle routing problem with delivery time windows. This consists of determining the production quantities at each site by minimizing the cost of transport and solving the sub problem. By considering an integrated approach, the computational results of a case study show a 25.33% percent decrease in the total cost production.Abstract: Our research focuses on the development of two algorithms based on the mathematical programming and local search procedures for resolution the Multi-Item Capacitated Lot Sizing Problem and Vehicle Routing Problem (MICLSP-VRP).

Abstract: On April 13, 2018, Hainan and Guangdong jointly put forward the idea of accelerating the construction of Qiongzhou Strait economic belt and realizing integrated and coordinated development. As the southernmost city in the mainland of China, Zhanjiang is only one sea away from Hainan, they are close to each other in culture, geography, rich in tourism resources and distinctive product features. Both of them have good conditions for developing coastal tourism and winter vacation tourism. It is the common wish of both sides to promote the regional tourism integration of Qiongzhou Strait and build a tourism destination of Qiongzhou Strait. In recent years, under the guidance of the two governments, the two sides have carried out a lot of tourism cooperation, and the basic cooperation mechanism has been established. But at the same time, it also faces the problems of imperfect tourism infrastructure, homogenization of tourism products, imperfect tourism cooperation mechanism and so on. Therefore starting from Zhanjiang, this paper hopes to use Hainan free trade port, international tourism island and other policies to explore how to better explores the appropriate path for the integrated development of tourism between Zhanjiang and Hainan, thus enhancing the popularity and competitiveness of Qiongzhou Strait Tourism at home and abroad.Abstract: On April 13, 2018, Hainan and Guangdong jointly put forward the idea of accelerating the construction of Qiongzhou Strait economic belt and realizing integrated and coordinated development.
