**1. Introduction**

The optimization in industrial process reduces and eliminates a lot quantity of failures and errors, generating more control in any step of the manufacturing areas. The majorly of the times are used specific improvements tools, as Ishikawa diagram and control graphs, principally; and in this times is used information and communication technologies (ICT) as complement of the optimization of the fabrication processes, with software to simulate the industrial activities, before applied in the industrial processes of any type of industrial company [1]. This has been to optimize the industrial operations and supports greatly to the industrial plants, where software have developed by specialized programmers, simulating the functionability of each step of the manufacturing processes and to have an idea of the industrial operations, as the possible fails and errors to

avoid unnecesary costs [2]. One of the most important industries worldwide is biomedical, which manufactures various devices used in everyday life in the SME biomedical industry of the Mexicali city [3]. There are much software to simulate industrial operations with design and test functions, being one of most used in the industry for the design of equipment, machines and tools, the COSIMIR software. This software contains basic and specialized functions with illustrations are made for industrial certain operations. In this investigation, this software was used to design a new work table, being developed in a special step of a manufacturing line out of the conveyor belt where biomechanical knee pads were organized in a plastic container divided into sections. This evaluation was made because, in this industrial operation, they were presented high indices of deffective products manufactured, before be organized in the containers, for the rawhen processing them quickly as the operation of the conveyor belt. Due to this, the following operations on the conveyor belt could not be developed by workers, causing delays in delivery to the following areas and to the customer. This generated concern in managers and supervisory personnel, the solution being the implementation of a work table in an annex place at the conveyor belt where it previously was made. One aspect observed was the evaluation of development of operations with security and comfort, analyzing the movements and postures of workers in each operation of the new workstation as ergonomic way [4, 5]. This caused at first, a greater concern of the operating personnel by the possible presence of a fatigue and stress, by inadequate postures and quantity of movements but was solutionated by ergonomic methods, to elaborate the activities in a manual way adequately, with correct light as is showed in **Figure 1**.
