Abstract
The contract furnishing sector ?stores, hotels and public facilities? is characterized for working under a MTO philosophy, having worldwide clients, a flexible and highly manual process and a high mix of products. In the presence of these sources of variability, the lack of a proactive planning drives to outsourcing and cost overruns. This paper presents a case study of capacity assessment in a Spanish SME of manufacturing, distribution and assembly of contract furnishing. To do so, a Monte Carlo simulation approach was adopted, with stochastic values for demand, process and product parameters. Based on historical data and expert interviews a spreadsheet-based model was proposed in order to represent the variability. As a result, capacity anticipation under different scenarios was provided (i) at present conditions, (ii) with an increased demand and, (iii) in case of a change in the type of production orders.
