The approach to the problem is new in a sense that the techniques of user modelling, adaptive system and group decision support will be used and adapted to the scheduling process in manufacturing environments. A scheduling module outputs a set of candidate scheduling solutions, each generated based on specific criteria and/or by a particular method. Scheduling is a multi-criteria decision problem in practice where different schedulers may agree on key objectives but differ greatly on their relative importance in a particular situation. The selection of a scheduling solution is achieved through the interaction among scheduling actors which is supported by a group decision support module considering the different necessities and the diversity of information source of each group or individual user","PeriodicalId":184726,"journal":{"name":"2007 IEEE Symposium on Computational Intelligence in Scheduling","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133612357","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 realistic scenarios of operational disruption management (DM) the high number of potential options makes the provision of online decision support complex. It is thus necessary to significantly reduce the size of the regarded (search) problems which can for instance be achieved by applying methods of partial rescheduling. However, existing approaches such as affected operations rescheduling (AOR) or matchup scheduling (MUP) focus on production-specific problems and can not be applied to more generic problem classes. To overcome this limitation, we introduce a novel approach to partial rescheduling in this paper: local rescheduling (LRS) is based on the incremental extension of a time window which is regarded for potential schedule modifications. We discuss how this time window can be initialized, extended and used for rescheduling. Moreover, we illustrate the superior performance of LRS in comparison with full rescheduling and MUP","PeriodicalId":184726,"journal":{"name":"2007 IEEE Symposium on Computational Intelligence in Scheduling","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134316156","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}

A conventional MPL form is required to recalculate the representation matrices by each job when applied to systems whose processing times differ by each job. Approximately twice the calculation volume is required to obtain the earliest and latest times using conventional MPL compared with our proposed MPL representation. This work assigns the state variables to events other than conventional ones, reduces the number of independent system parameters in representation matrices, and improves the form to schedule efficiently, even when applied to systems whose processing times differ by each job.

Partial rescheduling (PR), which involves only partial unfinished schedules, is adopted in response to each disruption and forms a PR sub-problem. The remaining unfinished schedule is just right-shifted or not following the solution of PR sub-problem. During the process of schedule execution, a rolling PR strategy is driven by disruption events. Each global rescheduling consisting of two segments of local rescheduling revises the original schedule into a new schedule, which is exactly the next original schedule. Two types of local objective functions are designed for PR sub-problems locating in the process or the terminal of original schedules respectively, where the global information of bi-criterion problems is reflected to an extent. The analytical results demonstrate that each local PR objective is consistent to the global one. For PR sub-problems with such a particular criteria, a genetic algorithm is used to solve it. Extensive computational experiments were performed. Computational results show that the rolling PR can greatly improve schedule stability with a little sacrifice in schedule efficiency and consistently outperforms the rolling right-shift rescheduling. The rolling PR strategy is effective to address large-scale rescheduling problems with more disruptions","PeriodicalId":184726,"journal":{"name":"2007 IEEE Symposium on Computational Intelligence in Scheduling","volume":"34 13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123145445","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 addition, some of the tasks have precedence constraints that require other tasks to be scheduled first. In this paper the refinery scheduling problem is addressed using genetic algorithms and cooperative coevolution.

The new algorithm handles two hard constraints: 1) avoiding examination clashes and 2) respecting the given maximum seating capacity; while simultaneously minimizing two objective functions: 1) the overall length of the examination period and 2) the total proximity cost An order based representation with a greedy decoder ensures that neither of the hard constraints is violated, and produces only feasible timetables. At the same time the dual objectives are attacked and the multi-objective evolutionary algorithm (MOEA) attempts to pack all the examinations into as short a period as possible while, at the same time, favoring a good spread of examinations for individual students. Most other published timetabling algorithms require the number time slots to be fixed in advance of any optimization for soft constraints, such as proximity costs. Smart genetic and heuristic operators used in the present study ensure that a good set of non-dominated results is produced by the new MOEA, covering a range of timetable lengths","PeriodicalId":184726,"journal":{"name":"2007 IEEE Symposium on Computational Intelligence in Scheduling","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129820399","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}
