From these, 40,928,038 people with disabilities are economically active. Given the significant importance of people who are employed in the formal / informal work, we sought to examine whether companies are adapting their workstation according to the needs of their disabled employees. The nature of research is applied with a qualitative feature and presents a descriptive and based case study. To collect data regarding workplace, ergonomics techniques were used, such as anthropometric and workplace measurements, Nordic questionnaire and interviews. From these data it was possible to make a diagnosis by comparing anthropometric and workstations measures and taking into account the information provided by the user as his need to perform his activities. Finally it was possible to prove that the anthropometric dimensions of the participant does not conform to the dimensions of the workstation and thus were suggested some proposals for improvements to increase performance, safety and comfort of the interviewee.

The company selected for the case study is in the business of manufacturing home appliances. We developed a model of Binary Integer Linear Programming to the problem of balancing. The model was implemented in a spreadsheet, and the optimal solution obtained through the Software OpenSolver, which uses the Branch and Bound algorithm. Since the model does not include all operating constraints, developed balancing implementable optimal solutions on the basis of the model. The results show that increasing productivity occurred because there was a decrease in the number of workstations required to perform the operations compared to the existing line, and therefore optimal use of the capacity of the new line.

The study that follows, the technique uses Monte Carlo simulation to verify, before a scenario with uncertain variables, the economic feasibility of purchasing an automatic leather cutting into a tapestry. In the analysis, the projected future cash flows, leading to the conclusion that such an investment would be paid for with savings in payroll and better utilization of the raw material (leather), on the other hand there would be additional costs for maintenance and electricity needed for equipment . Then built up a simulation model, which was implemented in order to generate the probability distribution of the behavior of each of the predictor variables, Net Present Value (NPV), equivalent uniform Value (vaue), Internal Rate of Return (IRR), Discounted Payback and Simple. It was observed then that the balance between savings and additional spending enabled the recovery of investment in a period less than 5 years (83.20% chance for the discounted payback). The application of methods NPV, IRR and vaue was needed to complete the project investment is quite profitable, with 81.71% success rate as (NPV> 0), however analysis of the variability of distributions generated (coefficient of variation 114% for NPV) showed that, although profitable, investment is risky. Finally, we performed a sensitivity analysis to determine the variables that most influence the variability and predictive value of the variables. It is accepted then the investment, but with a commitment to stimulate sales and controlling its variability.

Many companies are struggling to absorb the growing demand of a warm market due to the limitations of its productive capacity. One of the ways to attract customers is through the enterprise expansion. Thus, it is necessary a study to analyze the economic and financial feasibility and the sensitivity of the company's expansion. The values for NPV and IRR respectively equal to R$210,350.46 and 8.09% per month meet the expectations of the company's management, as well as the simple and discounted payback equivalent to 16.6 months and 17.5 months, within less than one year and a half, considered acceptable. Accepted the project, but must consider the uncertainties involved. In this sense, seeks to include a study of the risk inherent in the project through a sensitivity analysis using the graphical techniques Tornado Diagram and Spiderplot Diagram for determining which input variables causes more impact on the final result expected. Both techniques have converged to the same result showing that the sale price and the quantity sold deserve closer monitoring of managers throughout the project. Thus, one should seek ways to encourage sales so that such decisions can greatly influence the expected result, both positively, making it even more interesting, and negatively, making it uneconomical.
