It develops a methodology, which applies the methods of analysis processes, under conditions of uncertainty and considering the integration of processes, to serve as a tool for decision-making, in the process of macrolocalización plant. There are methods used at each step, the mathematical model of the problem, applied to a case study and software developed to support these studies. [ABSTRACT FROM AUTHOR]

In the present work is carried out a study of the demand of High Density Polyethylene at national scale, and in a particular way in the provinces of Ciego de Ávila and Camagüey aimed at predicting the capacity of a plant for the production of polyethylene of high density from ethylene obtained by means of the alcho-chemical Route. For it, it was applied the Method of the Initial no-Null Demand, proposed by Rudd and Watson, starting from the polyethylene consumption in the main industries. To minimize the financial uncertainty it was carried out the analysis parting from an interest rate of 0.15, with values above and below this (0.12 and 0.18). It was used, also 20 % -over designs value , recommended by Rudd and Watson for the Classic Design. [ABSTRACT FROM AUTHOR]

In this work a general methodology is offered for the application of the linear programming mixed with integers to solve problems related to sugar diversification, which may be applied to a sugar mill associated to a definite zone or to a province. This methodology was already put into practice in Noel Fernández Sugar Mill as part of its diversification project. The criterion of optimization used was to obtain the maximum profit. The constraints of raw materials, energy and steam were considered. Many alternatives were taken into consideration and the two best ones are shown here. [ABSTRACT FROM AUTHOR]

A study was carried out aimed at the macrolocalization of a plant for the production of alcohol in the province of Camagüey. The study was based on the transportation of the major raw material-final molasses, by using Solver, a computational tool of linear programming of the professional package EXCEL. As a result, all the possible alternatives for the location of the plant are offered, out of 12 that were considered, for a minimum transportation cost for each one, the industrial complexes, and the necessary amounts of final molasses required. This study is of great importance for the future development of this production in Camagüey. [ABSTRACT FROM AUTHOR]

This work has been carried out in order to obtain clean technologies in the productive process of ethanol starting on the merging of the environmental management tools and total quality one to the analysis process, propitiating favorable scenery to increase the application level of solutions of proactive character, achieving positive global impacts. The applied strategy was based on ISO 9000 Quality management and 14000 environmental management rules. The main problems of the process were identified which generate an inadequate technical, economical and environmental development of industry through the evaluation of technical, economical and environmental indicators of the productive process. Also were evaluated different alternatives to solve those problems. The main problems identified were: contamination by CO2 and wastewaters of distillation process, also the low efficiency and the over consumption of water in fermentation stage. The following order of alternatives was suggested for its application: recover of CO2, cooling system for water in fermentation and the automatic control of the mixer, which were generated through the evaluation on integrated form of technical, economical and environmental aspects.

Economic efficiency of two biogas plants working in Camaguey now was evaluated, the principal aim for its construction was gas use for energy purpose, and plants are feeding with cake filter and cow manures. Initially effluent use was not considered. The evaluation takes in count obtained information from plants proprietary and personal who exploit it. It was simulated the exploitation of all plant potential and obtained products. [ABSTRACT FROM AUTHOR]

In the present work was defined a scientifically-based methodology that applies the methods of the Complex Analysis of Processes, under conditions of uncertainty, which constitutes an important contribution. In its own application it is attempted to implement novel methods for the determination of production capacities, the macro-localization of plants and selection of alternatives of production and investment, with approaches of uncertainty, which is also a contribution of the work. The current advantages of the computer are used to solve the outlined problems. [ABSTRACT FROM AUTHOR]

In this paper a comparison between two methods for estimating measurement uncertainty and its effect in mass and energy balances in sugar mills is carried out. It was developed in Agramonte sugar mill, during ten days of January 2002. Monte Carlo simulation method and ISO-GUM method were used for obtaining uncertainty. By applying hypothesis test both methods were compared. It was demonstrated either Monte Carlo method or ISO-GUM method can be used successfully. A spread- sheet in Microsoft Excel was elaborated for developing this complex task. [ABSTRACT FROM AUTHOR]
