2 Littlefield Technologies Littlefield Technologies is a factory simulator that allows students to compete with each other over the web while developing operations management skills.Littlefield Technologies was developed by Dr. Sunil Kumar and Dr. Samuel C. Wood at the Stanford Graduate School of Business.Stanford has licensed the simulator to Responsive Learning Technologies, which has implemented it in a way that multiple universities can access it over the web
3 Littlefield Technologies It is most commonly used in courses that include the following:Operation ManagementManagement Science/Operations Research/Quantitative MethodsProduction and Inventory ControlIndustrial EngineeringManufacturingLearning Objectives include:Utilization and queuingCapacity managementLead time managementInventory controlCash flow managementManaging customer responsiveness, etc.
4 Littlefield Technologies Littlefield Technologies is a job shop which assembles Digital Satellite System (DSS) receiversThese receivers are assembled from kits of electronic components procured from a single supplierThe assembly process consists of four steps carried out on three stationsBoard stuffingTestingTuning
5 Littlefield Technologies 4 stepsStep 1 consists of mounting the components on PC boards and soldering them at the board stuffing stationStep 2 is when the digital components are briefly tested at the testing stationStep 3 is when key components are tuned at the tuning stationStep 4 is when the boards are exhaustively “final tested” at the testing station
6 Littlefield Technologies All the stations consist of automated machines which performs the operationsYou may buy and sell any machineBoard stuffing machines cost $90,000Testers cost $80,000Tuning machines cost $100,000Selling retirement price is $10,000Orders arrive randomly at the factory and each order is for 60 receivers which is then matched up with 60 raw kits and becomes a manufacturing lot
7 Littlefield Technologies If an order comes in and there are less than 60 raw kits, then the order waits in the customer order queue pending arrival of raw kitsEach kit is processed one at a time and does not move on to the next station until the entire lot is complete on the current stationOnce all stations are complete, the lot is then shipped to the customer
8 Littlefield Technologies Raw kits are purchased from a single supplier and cost $10 per kit ($600 per order) with a fixed cost of $1000 per shipmentThe supplier requires 4 days to ship any quantity of raw kitsAn order is placed when the following 3 criteria are met:The inventory of raw kits is less than the material reorder pointThere are no orders for raw kits currently outstandingThe factory has sufficient cash to purchase the specified order quantity
9 Littlefield Technologies The order is shipped when all 60 kits are complete for that orderIf an order is shipped out within 24 hours after it arrives, then $1,000 is earnedIf an order is shipped out after 24 hours of arrival, then a penalty is givenOrders that take longer than 72 hours will generate no revenue at all
10 Littlefield Technologies You will have some cash on hand when the assignment beginsThis amount is depleted by buying machines as well as buying raw kits from suppliersThe revenue comes from filled orders in the allotted amount of time and earns interest at 10% per yearThere are no taxes and all overhead costs are ignoredThe winning team is the team with the most cash at the end of the game
11 Registering Your TeamBefore the assignment begins you need to create and register your team (maximum = 3 students per team)You need a team name (all lower case letters and no punctuation) and a passwordOn the registration page, you will have to enter the code given in classThen you can enter your selected team name and passwordFinally, you will need to enter names of the team members
13 Using the Simulator The web-based simulator runs continuously One hour of real time corresponds to 24 hours of simulated timeYour factory is updated at login time and you can also click the update button on the bottom of the pageAssignment information is given to you before each assignment and while the assignment is running you can access the simulation as many times as you would likeOnce the assignment is over, the page is frozen and no more changes can be made
14 Using the Simulator Clickable icons are shown after login They reveal a menu and corresponding dataClicking on the icons will enable you to change certain features of the factory such as the number of machines in a stationSources and used of cash can be found here as wellFinally, you can check the overall standing of your team
