How do I find all the utility cost data? | Solution: The projsum.ICS cells 273 - 351 no longer report the individual utility resource costs. To view these you need to view the utility results in Excel. The projsum.ICS will still provide the total Utility costs in row 353.
To view the utility costs, you need to view the Investment Analysis results in Excel. Befo... |
Problem Statement: How to estimate components of different design criteria within the same project in Aspen Icarus Process Evaluator | Solution: Example. Two towers in a project have different flooding factors and tray efficiencies. Import the simulation data, and then before mapping, go to Develop>>Design Criteria. Scroll down to Trayed Towers, and set the flooding factor and tray efficiency for Tower A. Now right click on Tower A in the Process View... |
Problem Statement: How does Aspen Fleet Optimizer handle proportionality? | Solution: The goal of proportionality is to ensure that customer inventory is proportionate to the customer’s product sales.

Problem Statement: Aspen Icarus has design and cost models for single and double diameter towers. It may be necessary to generate costs for a tower with multiple diameters. | Solution: For a column consisting of three or more sections of differing heights, diameters, and wall thicknesses, consider combining sections to produce a two diameter vessel.
Run each of the columns separately in Aspen Icarus and tabulate height, diameter, wall thickness, combining diameters of two adjacent sections ... |
Problem Statement: Is it possible to specify text as the output from an If-Then-Else expression in the HYSYS spreadsheet? | Solution: New in Aspen HYSYS 2006.5, text values can be used in If-Then-Else expressions in the spreadsheet. For example, the expression @if(A1>100,flow is greater than 100 kg/hr,normal flow) will return the text normal flow if the value of cell A1 is 80.

Problem Statement: Compressor random flow under surge conditions causes model to fail in Aspen HYSYS Dynamics. | Solution: An option to disable random flow was added on the compressor Rating | Flow Limits pagetab in Aspen HYSYS 2006. Activating the Do not limit flow to surge/stonewall (only warn) check box allows the user to disable random flow. See the attached sample case and also the screen shot below:
Keywords: random, compre... |
Problem Statement: When I change the Process Complexity, my TOTAL PROJECT CAPITAL COST does not change nor do the details for my piping and instrumentation costs, etc. | Solution: Process description, Process complexity and Project type in Standard basis file affect the percent of contingency in the same file. The Total Project Capital Cost may change but items and their associated costs never change.
Please follow the version specific steps to change and apply the process complexity, ... |
Problem Statement: What is the warning manager feature used for in Aspen Fleet Optimizer? | Solution: The Warnings Manager stores warning messages that are created during the operation of Fleet Optimizer. Warnings information can be sorted and printed to help dispatchers address scheduling problems, data problems, or user errors. This function is used to help ensure data quality before planning, scheduling, a... |
Problem Statement: How does Aspen Fleet Optimizer use the data mode button? | Solution: The Data Mode (Radio Buttons) buttons notify the user of what data is being collected for forecasting each customer's shipments, such as sales, inventory, or both. A check mark in the center of the radio button shows the user what type of information is being provided for that customer, such as sales informat... |
Problem Statement: When I export my simulation case to Aspen Process Economic Analyzer (APEA), multiple areas are being created in APEA. Why? | Solution: When you export a simulation case from either Aspen plus or Aspen HYSYS to create a project scenario in Aspen Process Economic Analyzer (APEA), you might find that multiple Areas are created automatically. This is most likely due to the fact that the simulation case had hierarchies in a Global flowsheet (as i... |
Problem Statement: How can I control the warnings in Aspen Fleet Optimizer Data Quality Manager? | Solution: Override Warnings occur when the user overrides an exception by ignoring the variance and moving on without correcting it. When the Override Warnings option in the Options Menu is checked on, Aspen Fleet Optimizer displays two dialog boxes to remind the user to flag delivered shipments as delivered and assign... |
Problem Statement: What is sales test override used for in Aspen Fleet Optimizer? | Solution: The Sales Test Override value is used in inventory only forecasting. If sales of this product remain within the override percentage from expected sales for that day, the user will not be required to manually confirm delivered shipments in the data quality manager. The Sales Test Override value must always be ... |
Problem Statement: How do I set up what each role has access to in Aspen Fleet Optimizer? | Solution: To configure Aspen Fleet Optimizer Security:
Log into Fleet Optimizer using a user role that has been granted the AUMIM_SEC database role.
In Fleet Optimizer, select Utilities Security Utility from the main menu.
Double-click on a function and select the database role(s) that will have permission to use the ... |
Problem Statement: What is NPV (Net Present Value) value and how do I calculate it? | Solution: NPV is the result for accumulating the net earnings (NE) at a given period then modified by the interest rate. It is current worth of all the Net Earnings received through period n. The Net Earnings (NE) are funds available after taxes have been paid. This number is obtained by subtracting the Taxes from th... |
Problem Statement: How to delete areas in Aspen Process Economic Analyzer that were created while importing from a simulator (HYSYS/Aspen Plus)? | Solution: Currently, there is no way to suppress areas developed from simulator file. The only approach is to create a new scenario, and then bring the equipment into a single area in the new scenario.
To do this:
1) In the existing scenario, drag and drop all the equipment into the main area
2) Create a new scenario a... |
Problem Statement: Why can I not assign a carrier to truck in Aspen Fleet Optimizer? | Solution: Fleet Optimizer allows you to create profiles for frequently used carriers. By creating a profile that contains an email address, you can email Transport Tender reports directly to carriers from within RSO. Each carrier must be assigned to a terminal before it can be assigned to trucks in that terminal. If y... |
Problem Statement: How do I keep the unit of measurement (in metric units) of my Simulation case from changing to the Inch-Pound units when I send case to Aspen Process Economic Analyzer (APEA)? | Solution: When sending Aspen Plus / Hysys Simulation case to APEA, the default unit of measurement is US Inch Pound. This is because the default template used is the US_IP template file.
This could be inconvenient if user wishes to keep equipment details in their own metric specification. This can be resolved by chan... |
Problem Statement: How does Aspen Fleet Optimizer know if a product is available? | Solution: Products must be flagged available for the Transport Scheduling Optimization to schedule a transport to pick up product from the given terminal.
