This research is motivated by the need for considering lot sizing while accepting customer orders in a make-to-order (MTO) environment, in which each customer order must be delivered by its due date. Job shop is the typical operation model used in an MTO operation, where the production planner must make three concurrent decisions; they are order selection, lot size, and job schedule. These decisions are usually treated separately in the literature and are mostly led to heuristic solutions. The first phase of the study is focused on a formal definition of the problem. Mathematical programming techniques are applied to modeling this problem in terms of its objective, decision variables, and constraints. A commercial solver, CPLEX is applied to solve the resulting mixed-integer linear programming model with small instances to validate the mathematical formulation. The computational result shows it is not practical for solving problems of industrial size, using a commercial solver. The second phase of this study is focused on development of an effective solution approach to this problem of large scale. The proposed solution approach is an iterative process involving three sequential decision steps of order selection, lot sizing, and lot scheduling. A range of simple sequencing rules are identified for each of the three sub-problems. Using computer simulation as the tool, an experiment is designed to evaluate their performance against a set of system parameters. For order selection, the proposed weighted most profit rule performs the best. The shifting bottleneck and the earliest operation finish time both are the best scheduling rules. For lot sizing, the proposed minimum cost increase heuristic, based on the Dixon-Silver method performs the best, when the demand-to-capacity ratio at the bottleneck machine is high. The proposed minimum cost heuristic, based on the Wagner-Whitin algorithm is the best lot-sizing heuristic for shops of a low demand-to-capacity ratio. The proposed heuristic is applied to an industrial case to further evaluate its performance. The result shows it can improve an average of total profit by 16.62%. This research contributes to the production planning research community with a complete mathematical definition of the problem and an effective solution approach to solving the problem of industry scale.

The diploma thesis focuses on design of e-commerce solution and propagation for selected firm. New design is result of bad technical condition of old solution, which has not been supported with any possibilities of propagation. In last part thesis is focused on configuration for automatic reports of website performance and marketing activits.

The topic of this master thesis is the elaboration of the project documentation of the new construction of a multifunctional building of the registered office of the company. New building is situated on the land in Ružomberok in the area intended for production and warehouse function. The proposed facility represents the background for a company that is a leading supplier of spare car parts. The building consists of a three floors with a partial basement. 1.PP and the part of 1.NP are storage areas. The rest of the first overhead floor is the shop. The second floor represents the administrative part of the business. The last, third floor, has 3 corporate apartments of various inclinations. The object is based on the concrete strip foundations. The structural system uses the ceramic blocks of type Therm. The walls of the basement are made of a concrete structural system. The ceilings of the building are designed as cast-in-place reinforced slabs. Screed to fall of the flat roof is thermal insulation and the finish is made of pea gravel.

The diploma thesis is focused on the use of project management methods in the company during a pandemic. The aim is to create a project proposal for the creation and promotion of a new company website with a full-fledged online store in order to increase product sales. The theoretical part describes the individual concepts and methods that are used in the analytical and design part. The analysis of the company is processed in the analytical part. Based on the information obtained about the company, a project proposal is developed using project management methods.

Based on system analysis of modern e-business environment created by the proposal is evaluated in terms of e-commerce functionality and marketing.

The Master’s thesis deals with creating of business plan for starting and running a barber shop. The thesis starts with theoretical knowledge, which I use for following analysis of the market and creating a business plan. Business plan contains information about company, strategies and financial plan.

MUÑEQUERIA COUNTRY busca ofrecer productos diferentes, únicos y creativos para el hogar o para regalar, con precios accesibles con la más alta calidad en diseños y acabados. El proyecto inició con el Estudio de Mercado, a través del cual se determinó la existencia de una demanda insatisfecha, la cual puede ser cubierta por la empresa. El estudio continúa con el trabajo de investigación, lo que nos permite conocer la factibilidad de recursos financieros, humanos, físicos y capacidad de producción. MUÑEQUERIA COUNTRY contará con una oficina taller alquilado, el cual estará ubicados en el Distrito de Lince, se determinó este sitio a través de la matriz de localización. Por otro lado, el recurso humano que se requiere es factible. Los recursos financieros comprenderán un 40% por aporte de los socios y 60% por un préstamo bancario. Por último, plan Económico - Financiero, el cual determina la rentabilidad o no de la empresa. Se inicia con el presupuesto de Inversiones, donde Activos son (S/. 20,121.00), Gastos pre operativos (S/. 7,310.00) y el capital de trabajo (S/. 1,814.00), establecieron una inversión inicial de S/ 29,244.00. La evaluación financiera se realizó con el factor WACC 44.82%, obteniendo un TIR, VAN, COK y Período de Recuperación, que determinaron que la empresa si es factible. Es así que después del estudio realizado se llegó a la conclusión de que el proyecto es viable y que la implementación de “MUÑEQUERIA COUNTRY” es posible, por tanto, permiten la puesta en marcha de la empresa. / MUÑEQUERIA COUNTRY seeks to offer different, unique and creative products for the home or to give away with extremely affordable prices with the highest quality in designs and finishes. The project began with the Market Study, through which the existence of an unsatisfied demand was determined, which can be covered by the company. The study continues with the research work, which allows us to know the feasibility of financial, human, physical resources and production capacity. MUÑEQUERIA COUNTRY will have a rented workshop office, which will be located in the Lince District, this site was determined through the location matrix. On the other hand, the human resource that is required is feasible. The financial resources will comprise 40% by contribution of the partners and 60% by a bank loan. Finally, Economic - Financial plan, which determines the profitability or not of the company. It begins with the Investment budget, where the Assets (S /. 20,121.00), Pre-operating Expenses (S /. 7,310.00) and the working capital (S /. 1,814.00), established an initial investment of S / 29,214.00. The financial evaluation was carried out with the WACC factor 44.82%, obtaining an IRR, NPV, COK and Recovery Period, which determined that the company is feasible. Thus, after the study carried out, it was concluded that the project is viable and that the implementation of “MUÑEQUERIA COUNTRY” is possible, thus allowing the start-up of the company. / Trabajo de investigación
