 | Please, put here your assignments. Do not forget to sign them. You can use ~~~~ (four tildas) for an automatic signature. Use Show preview in order to check the result before your final sumbition. |
| Please, strive to formulate your assignment carefully. We expect an adequate effort to formulate the assignment as it is your semestral paper. Do not forget that your main goal is a research paper. It means your simulation model must generate the results that are specific, measurable and verifiable. Think twice how you will develop your model, which entities you will use, draw a model diagram, consider what you will measure. No sooner than when you have a good idea about the model, submit your assignment. And of course, read How to deal with the simulation assignment. |
| Topics on gambling, cards, etc. are not welcome. |
 | In order to avoid possible confusion, please, check if you have added approved in bold somewhere in our comment under your submission. If there is no approved, it means the assignment was not approved yet. |
Simulation proposal (dolj04)
Topic/goal: Optimal size of HDD for virtual Digitization server
Definition of the problem:
- each day an average of 47 batches of documents is being processed by the server with average size per batch of 32 MB (calculated from customers server)
- the number of batches changes a lot and cant be easily predicted so it will have to be taken into consideration (from sample: lowest number of batches scanned in a day is 13, the highest is 134)
- the average size is not changing that much
- (batch contains original scanned documents, extracted data in XML files, log files, enhanced images and searchable PDF)
- backup images from scanning will stay on the server for 6 months (those are additional ~50 % of the batch size)
- successfully processed batches older than 14 days are deleted every day
- for precaution lets say around 5% of batches wont be processed correctly
- those will stay on the server and will be processed every month by admins
Simulation environment: Vensim
