This paper presents an option for improving the process of assigning storage locations for merchandise in a warehouse. A disadvantage of policies in the literature is that the merchandise is assigned allocation only according to the volume of sales and the rotation it presents. However, in some cases it is necessary to deal with other aspects such as family group membership, the physical characteristics of the products, and their sales pattern to design an integral policy. This paper presents an alternative to the aforementioned process using Flexsim ® , artificial neural networks, and genetic algorithms. OPSOMMING'n Metode om die toekenningsproses van stoorplekke vir goedere in 'n pakhuis te verbeter, word voorgehou. 'n Nadeel van die bestaande beleide in die literatuur is dat die goedere slegs toegeken word op grond van die verkoopvolume en die omset wat dit verteenwoordig. In sommige gevalle is dit egter nodig om ander aspekte, soos familie groeplidmaatskap, die fisiese eienskappe van die produkte en hulle verkoopspatroon, te oorweeg om 'n integrale beleid te formuleer. Hierdie artikel beskryf 'n alternatief vir die voorafgenoemde proses deur van Flexsim ® , kunsmatige neurale netwerke en genetiese algoritmes gerbuik te maak.

The aim of this work is to present a concise analysis of Quality control circles (QCC's) disuse in the Mexican Industry. Design/methodology/approach-A comparative descriptive analysis was carried out on the year of 2000 and 2015, considering a sample of Mexican Industries that implemented the quality control circles, which belong to the Mexican Association of Work in Team A.C. (AMTE). First, in the methodology was realized a classification of the sample studied, later it was divided into two stages: 1) Quantitative variables and 2) Qualitative variables. Findings-Two important factors can be considered to explain the QCC's disuse. (1) The different cultural context. (2) The new and better methodologies currently recommended for the solution of opportunity areas in Mexican Industry. Finally, the few Mexican Industries that uses Quality Control Circles suggest consider a high percentage of employees to guarantee adequate results. Discussion-A first possibility to consider a clear tendency to disappear the QCC in Mexican Industry is due to a different cultural context. A second possibility could be to better methodologies are currently recommended for the solution of areas of opportunity. However, the fact that, apart from the automotive sector and its derivative components, the participation of another industries turnaround has been drastically reduced to almost disappear, as well as for the service companies.

The simple act of walking can occasionally cause ankle sprains. Traditionally, the rehabilitation of a sprained ankle involves physical therapy. Physical therapy is one of the health professions that help regain mobility through manual exercises. Aquatic therapy is one of the most potent water-based anti-inflammatory methods currently employed that increases local blood circulation, decreases pain and swelling, and promotes speedy healing. Several studies have demonstrated that ankle rehabilitation robots have immense potential in patients’ rehabilitation and recovery; however, these robots cannot be used underwater. This paper introduces the design, development, and control of a therapeutic robot incorporating aquatic therapy for ankle rehabilitation. Its primary objective is to design and control a one degree of freedom ankle rehabilitation robot that can be used in water and can recirculate hot water to simultaneously perform physical therapy and aquatic therapy. To conduct this study, an ankle rehabilitation robot was designed, modeled, developed, and controlled. The design and control techniques were evaluated by means of simulation and experimental results.
