A thesis deals with simulation modeling. After opening theoretic information about models, discrete and continuous simulations, computer technologies for systems modeling and individual phases of simulation process, there follows a case study, which demonstrates using of three software products for simulation modeling -- SIMUL8, Simprocess and Powersim Studio. Created models, experiments with them and given results, including well-arranged tabular comparison of mentioned computer programs according to defined criteria, point out strengths and weaknesses of each software. Simultaneously, data for selection of an appropriate program are presented, depending on a sphere type, which is simulation modeling to be applied on.

The issue of the work is use of simulation methods in real situation. First part of thesis belongs to explanation of warehouse technologies and simulation techniques used in the work. Follows a transformation of real enterprise warehouse to computer simulation model. The main part is focused on experiments on this model which solves real problems in this warehouse. Target of first experiment is to find solutions to shorten the waiting time of trucks. This is accomplished by series of experiments, which are compared and the best solution is selected. Another three experiments contains future or hypothetical situations in the warehouse. On the basis of the simulation results future steps and preparations are proposed.

Eniro 118 118 AB is Sweden's largest enlightenment company. The company provides numerous operator-based services in addition to their main service 118 118. For a service company like Eniro 118 118 AB, the telephone operators required to provide its services represents a significant proportion of the total expenses. It is therefore of great interest for the company to maintain these costs at lowest possible levels. The current business cycle along with competition from new companies and new technological possibilities for its customers has led to a situation where the importance of an efficient resource planning is becoming increasingly more significant. The dilemma lies in the complexity and versatility of the operating system. A large number of telephone operators with a unique set of core skills are working simultaneously in three different systems that interact with each other according to certain predetermined rules. To determine the number of telephone operators required at any given time for each service is very complicated.The purpose of this thesis is to provide the planning office in Sundsvall with a tool that facilitates the resource planning activities on a daily basis. This is to be done by constructing a simulation model that looks and behaves like the real system, combined with an easy-to-use user interface that allow planners to test various staffing scenarios in a safe environment.The first step was to accurately create an understanding of, and to record exactly how Eniro 118 118 AB´s telephone system is structured. A number of interviews were conducted with the supervisor at Eniro 118 118 AB, who also provided certain documentation and lots of statistics. Additional interviews with stakeholders in the planning office were made in order to clarify how the user interface was to be designed, what parameters to make adjustable, and the types of results to be presented. The simulation model has been developed in the Simul8 simulation package as requested by Eniro 118 118 AB. The model has been designed to handle all requirements defined by the company and offers a complete tool for testing different staffing scenarios in a safe environment that behaves just like the real system. The user of the simulation model specifies input data such as operator availability, phone call arrival rate, average operation time and setup time for each service. After being run, the model will present the following results; operator workload, level of service and average wait time. The simulation model communicates and is controlled by MS Excel, which means that users do not need to learn Simul8 in order to use the product. Considering Eniro 118 118 AB’s requirements for documentation, a manual has been prepared which in detail describes how the simulation has been constructed and how Simul8 operates. This is to facilitate a possible future scenario in which current conditions no longer apply and the simulation model needs to be modified. / Validerat; 20111011 (anonymous)

Práce vystihuje teoretické poznatky z oblasti teorie hromadné obsluhy a simulace a následně jsou aplikovány poznatky do praxe. Pro případovou studii je využíván simulační software Simul8 a podpůrný program Crystal Ball, pomocí nichž je vytvořen model. Cílem je navrhnout nejlepší řešení daného problému a zhodnotit systém z hlediska struktury a funkčnosti. S modelem je provedeno několik experimentů a následně je posouzena vhodnost či nevhodnost použití jednotlivých variant.

The aim of this thesis is to analyze and optimize production processes in a company which produces plastic components for the automotive industry. The theoretical part of this thesis summarizes basic knowledge of business process simulation and addresses the reasons for making use of dynamic simulation as a tool for eliminating dissipation and supporting decision making. The main focus is an analysis of the current situation and identifies the problems in the company. For the purpose of optimization, a simulation model was created using Simul8, by the Simul8 Corporation. The model was made in accordance with the methodology described in the theoretical part of this thesis. It was used to examine the efficiency of proposed versions of the production schedule, in light of its impact on storage capacity and service level.

Diplomová práce se zabývá simulací výrobního procesu, zejména stanovením potřebného počtu personálu. Popisuje jednotlivé části simulačního projektu. Teoretická část je věnována generování náhodných čísel a jejich transformaci v požadované statistické rozdělení.

Simulation models are used to analyse company processes. The purpose is to create a model in simulation software that will represent the behaviour of the company. Options to improve the current situation are investigated by observation of the studied system and subsequent experimenting with the model. This work deals with the situation in the company, which focuses on lease and service of working platforms. New headquarters is being built to provide better services and changes in offer of leased working platforms are being considered. Model of the company is created in software SIMUL8. Next step is to perform simulation experiment and summarize the results. Input values are adjusted according to these results, which leads to a more favorable solution. The aim of this work is to optimize the working capacity and improve the structure of offer of leased working platforms.

Předmětem diplomové práce je nastínit základy simulací, modelů hromadné obsluhy a fungování zákaznických center. V praktické části je použit k úpravě získaných dat software Crystal Ball, pro samotnou simulaci a analýzu Kontakt centra Karneval pak simulační program Simul8.

This diploma thesis deals with the solution to a real situation that occurred at Nemocnice Na Františku in Prague. The problem is solved by using a computer simulation in SIMUL8 simulation program. At the beginning I describe the theoretical foundations that are afterwards used as a basis for the main practical part. The main subject of the work is a simulation of an operation of the hospital outpatient department. The hospital management decided to change the system for handling patients operations. I have created simulation models for particular workday and weekend means of patients serving operations. The created simulation models and their outputs are evaluated in the final part of the thesis and will serve as a basis for making reorganization decisions in the hospital. The provided advice for hospital management fulfills the goal of this thesis.
