Problem Statement: We use tiered pricing for purchases and sales in our Aspen PIMS model, but we want to control the order in which they are sold. For purchases, by default, less expensive tiers are purchased before more expensive tiers. For sales, the default behavior is the opposite: higher-priced tiers are sold befo... | Solution: Tiered pricing uses Table ALTTAGS to define aliases for purchases and sales. In order to define different prices for a given material or utility, different tags must be used in Tables BUY, SELL, UTILBUY or UTILSEL.
The default ordering of buying or selling these tiers is determined by economics. Because the... |

Problem Statement: When running many cases (more than 80) in big models, especially for PPIMS, MPIMS or XPIMS, it can happen that Aspen PIMS crashes. One possible cause of the crash is that the maximum size of the Results.mdb is reached. The Results.mdb, as any Microsoft Access database, has a 2 gigabyte file size limi... | Solution: One possible solution to avoid the crash is to review the size of the Results.mdb for one case. A good approximation is that the total size of the database will be the database size created for one case, times the number of cases. If that goes close to the 2 GB limit, you need to run fewer cases at a givne ti... |
