STEPS TO FOLLOW7 STEPS PROGRAM11. Establish the commitment to invest2. Clearly state the problem3. Determine the type of tool required4. Do an initial survey5. Develop the list of requirements6. Choose some tools7. Carry out a detailed evaluation 2014 Critical Manufacturing S.A. All rights reserved.

DETAILED EVALUATIONSOURCES17Trials/DemosDirect ContactExperimenting the software, doing someexamples and demos.Direct contact with the vendors in orderto get informations they don’t provide inthe website.Information from SiteWeb SearchEach product website has some relevantinformation about the software.More but discarded solutions were foundthrough web seacrh.Papers and JournalsGuidesConsulting some papers and journals inthe field was one of the best methods togather information.To learn how to proper work with thesoftware, the application guides and somevideos were studied. 2014 Critical Manufacturing S.A.

ANYLOGICPROS AND CONS117Advantages and Extra FeaturesLimitations and DisadvantagesAllows three types of modelling: AgentBased, Discrete Event and SystemDynamicsDoesn’t allow WCF communicationBecause of that, allows all types ofsimulations (Discrete/Continuous,Micro/Macro Level, )Difficult to use, requires a large study ofdocumentation and tutorialsSimulator with the most well-knownclientsExtend default models with Java 2014 Critical Manufacturing S.A.

IN-HOUSEPROS AND CONS122Advantages and Extra FeaturesLimitations and DisadvantagesAllows WCF communicationSolution that doesn’t have market proofsProbably the cheapest solutionCan become obsolete if not upgradedregularlyCan be adapted to meet all Critical needsand requirementsHigh risk of developing software fromscratchSolution adapted to the Critical codingguidelinesOnly works with Critical’s softwareCan be adapted to each new productdeveloped by CriticalWill not have the level of functionalitycompared to a commercial-off-the-shelfproduct 2014 Critical Manufacturing S.A.

IN-HOUSE1TASKS’ PRICE23NameDescriptionRiskCost (inman/hours)Technologies’StudyAn initial study of the technologies to beused has to be made. This includes thestudy of cmNavigo, the programminglanguages to be used, the Stress Test andMasterData already developed and thedifferent simulators in the market.High64 - 8 daysT02ArchitectureDesignSince this is a one man job, thearquitechure will serve more to explain tothe client what’s the global vision of thesolution, nevertheless this is an essentialstep of every project.Low32 - 4 daysT03TechnicalRequirementsThe requirements already agreed are onlymacro-tasks, the technical ones are yet tobe discussed.Medium16 - 2 daysModelDevelopmentIn order to achieve the best simulationpossible, it’s necessary to have a robustsimulation model behind. So is devotedenough time to choose the bestapproach, as well as the design of themodel for that approach.High80 - 10 daysIDT01T04 2014 Critical Manufacturing S.A. All rights reserved.

This macro-task will be dividedas specified on T03.High360 - 45 daysTests with TestDataIt is important to validate the applicationwith test data to be able to understand ifeach module is operating correctly. Therewill be two stages of validation with testdata, the first one to validate the modeland the second to validate the simulator.Medium40 - 5 daysTests with RealDataThe validation will only be completedwhen it is possible to simulate a realfactory with precision. In order to do thatit’s necessary to test the solution withdata from a real company.High80 - 10 daysDocumentationThe final documentation is the final stepof every project. All of the steps that leadto the development of the solution haveto be documented and an user-manualhas to be written.Low64 - 8 daysT06T07T08 2014 Critical Manufacturing S.A. All rights reserved.

CONCLUSIONSWHAT TO CHOOSE1All commercial simulators have the same big issue: they don’tallow direct communication with cmNavigo, but some can workwith dll’s. Is it better to invest in an off-the-shelf product that has marketproofs or develop one from scratch that is built arroundcmNavigo? Will CM be dependent of an external company if choose acommercial simulator? Can an one-man-simulator have the power of one built by onelarge company? 2014 Critical Manufacturing S.A.
