The promotional work “Optimization Methods and Models Creation for Logistic Company Successful Development” has been worked out by Olga Girvica to obtain the scientific degree of Doctor of Science in Engineering. Scientific supervisor of the work is Dr.hab.sc.ing., professor Alexander Andronov. Due to specific geographic location of Latvia transport area plays one of the main roles in the national economy and also important for the economical development of the whole European Union. High attention is paid by the government for development of Logistics in Baltic area. A broad area of my research is the lack of practical methods for optimization of the costs and activities for the logistics centre in the market conditions of World recession in Latvia. There are some specific tasks for Logistic centre successful development and design together the facility and delivery process to better reveal and support of customer purposes. One of the main objectives for any logistic company is to simplify the supply chain, minimize storage and maximize speed and efficiency for delivery of goods. Warehousing and distribution is an important part of any supply chain. The essential part is the information technology and efficient flow of information between the members of the chain as well as understanding the business and needs of clients. The goal of research is to develop of the new optimization models for solving the tasks of logistic company in the market conditions of World recession. Development of the new logistic models enables planning of the optimal use of any business resource (vehicles, finance and others), also minimization of the business costs and maximization of the received profit. This helps for modeling of a complete logistics system (chain) from the raw materials producer till the recipient of the end product. The models can be used both within creation of the overall transport system development strategy and within solution of specific related tasks. Using the methods of mathematical programming three new models for work optimization of logistics companies were presented. 1. The design of optimal circular routing for goods delivery. Using the method of stochastic optimization a new Mathematical model for Optimal Planning of Circular Delivery Routes was suggested. Using this model the optimal route which provides the minimal delivery destination for each group of the delivery points was made. Differ from well known “task of commercial traveller” our problem is more complex because additionally it takes into account many cycles, weight of goods and a weight restriction for each cycle and valuable by its singularity (originality). Considered decisions and right strategy for creating of circular delivery route for goods distribution from Logistic centre to final customers allow to decrease the costs and optimize the work of the Logistic centre by more effective use of transport and minimization of goods lean time. 2. The model of hierarchic optimization of the resources distribution among the units of the Logistic centre. The problem of resources distribution in optimal way among the units of the Logistic centre which has the treelike structure was solved with help of this model. There are some various ways of development for each unit of the Logistic centre. The ways differ from each other by necessary resource and profit receiving. 3. The Logistic centre Supply Chain optimization model. The model allows solve the task of the decision-making process for Logistics centre Supply Chain optimization through the creation of the new supply and sales channel in optimal way. There are some various decisions could be taken at each stage of process development. Two aspects, such as maximum probability of the best effect achievement and average profit maximization are taking as the criterions for effectiveness of making decisions. Acquisition and development of the optimization models and methods of the vehicles use and logistics centre activities is a significant step for securing optimal planning and further successful development of the transport system in Latvia and EU.
