This means a practical difficulty of changing tools and production lines frequently. Here, a study has been carried out to find out the changeover time and the kinds of wastes in the sewing line. For two months, a series of observations and analyses of two garment factories has been taken in order to identify wastes and to eliminate them. Lean manufacturing and SMED technique are two methods that have been considered as guideline to solve those problems. Serious problems have been detected in studied sewing lines: the technological constraints due to the skill level and efficiency of mechanic's labor and the working process.","PeriodicalId":339666,"journal":{"name":"2013 5th International Conference on Modeling, Simulation and Applied Optimization (ICMSAO)","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125108339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems are known to be very expensive because of using several pre-recorded hours of speech. Hence, building a model that minimizes the cost of the recognizer will be very interesting. In this paper, we present a new approach for recognizing speech based on belief HMMs instead of probabilistic HMMs. Experiments shows that our belief recognizer is insensitive to the lack of the data and it can be trained using only one exemplary of each acoustic unit and it gives a good recognition rates. Consequently, using the belief HMM recognizer can greatly minimize the cost of these systems.","PeriodicalId":339666,"journal":{"name":"2013 5th International Conference on Modeling, Simulation and Applied Optimization (ICMSAO)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125470738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calls have a non-preemptive priority over emails. The call service is characterized by three successive stages where the second one is a break, i.e., there is no required interaction between the customer and the agent for a nonnegligible duration. This leads to a new opportunity to efficiently split the agent time between calls and emails. We focus on the optimization of the email routing to agents. Our objective is to maximize the throughput of emails subject to a constraint on the call waiting time. We develop a general framework with two parameters for the email routing to agents. One parameter controls the routing between calls, and the other does the control inside a call. In particular, we prove for the optimal routing that all the time at least one of the two email routing parameters has an extreme value.","PeriodicalId":339666,"journal":{"name":"2013 5th International Conference on Modeling, Simulation and Applied Optimization (ICMSAO)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116550982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present novel models with a new reading of the problem. Indeed, some classical models in literature seem in certain cases simplistic and then generate gaps between theoretical formalisms and the reality. Concretely, these gaps arise when setting up and calibrating these models, thus the identification of robust parameter values could prove difficult. The reason is the aggregation process of data, since it is naturally used in modeling, lacks to provide sufficient accuracy. In a pragmatic framework, the issue of logistic network design is rich and presents several possibilities for data apprehension in terms of details to be modeled. This motivates to construct a more realistic modeling approach. In this context, we propose a way for integrating a maximum precision degree without leaving the context of modeling a strategic issue. Actually, the question of designing a logistic network is substituted by the need to compute a logistic master plan mixing the tactical with the strategic. This becomes a major concern of businesses and this observation fits the importance of location-allocation problems. Two mixed integer programming (MILP) are proposed. A derived linear programming (LP) is identified and used to describe a perspective of a cooperative hybrid resolution approach based on Genetic Algorithm. Experimental study provides a comparison of the models results.","PeriodicalId":339666,"journal":{"name":"2013 5th International Conference on Modeling, Simulation and Applied Optimization (ICMSAO)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114966251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a genetic algorithm (GA), the so called genetic algorithm with two-point crossover (GA2P), for this problem that is able to provide near-optimal heuristic solutions.

The Priority Ceiling Protocol (PCP) is applied as an approach to ensure the scheduling between periodic tasks with precedence and mutual exclusion constraints.

To evaluate the performance of the selected features, experiments were performed using a Multi-Layer Perceptron (MLP) classifier with Feed Forward Back Propagation training algorithm (FFBP). The developed method was evaluated using voice data base composed of recorded voice samples (continuous speech) from normophonic and dysphonic speakers.
