 Tutorial 6Evaluation and reporting Learning goalsUsing the INCASE, THEN and ELSE functions.Using the SORT# function.Creating reports using the WINWORD\$ function.

# 1    Objective

In this tutorial we will evaluate the systematic variations of the design using a weighted average of all parameters describing the compatibility of the ships. Then we'll sort the designs in order of compatibility and finally a report is created in MS Word for each design.

### Start

To start this tutorial, a knowledgebase is available [Tutorial 6 start.qkb]. This knowledgebase contains the results of tutorial 5 and is the basis for this tutorial.

Also a Word template file (Report.rtf) has been provided. Make sure you save this file in the Applic directory of your knowledge base so it can be found during calculation.

# 2    Create a new Dataset as starting point

Create a new object Ship_evaluation. Add this to the list of the present Data object in Dataset (you can either leave the existing Shipsobject or delete is). Make sure that the Determined by property of Ship_evalation is OBJ, otherwise you will discover later on that the data inside the object is not taken to the solution.

1. Add the following parameters to the knowledge base:

• Stab;
• Comf;
• Rt;
• PE;

All parameters are values and the "Determined by" of Slots & Properties should be OBJ because they should be taken from the dataset. Stab and Comf are without a dimension. Rt is in [N] PE is in [W]. Move Stab and Comf to the Stability class, Rt and PE to the Resistance class.

2. Now add data to the dataset that we are going to use during the calculations:

...

# 3    Evaluation of the designs

Create the following evaluation relations:

• Efficiency = 1 + 25.7 - (PE / (DISP * V_eco) * 2.25)

• Journey = 1 + (28 - (10000 / V_eco / 24)) * 2.25

• Grade = INCASE(GM,LT,0.4,THEN,0,ELSE,(Stab + Comf + 1.2 * Journey + 1.2 * Efficiency )/4.4)

Add the evaluation parameters as goals to the Ship_evaluation object using a relation:

Sort the ships, based on their grade

To check whether all this works, carry out a calculation. Start the process manager. Select Data and select Sorted_evaluation#. The content of Sorted_evaluation# will be:

# 4    Check the template file of the report, create a report

Open the file (Report.rtf) in MS Word to take a look at it. All kind of parameters between # are visible. Moreover, a Boolean expression is used in: #GM<0.4[1]#INSUFFICIENT[1]: When GM is smaller then 0.4, the text INSUFFICIENT is shown. More information on the possibilities with templates is given in the description of the function TEMPLATE\$() in the wiki.

This template should always first be checked on strange RTF code. Use the menu item Tools>RTF Template Check... You will be asked to select a file and the Template delimiter (usually #, as in our file). Then Quaestor will check,  rovide a log file and store the original and changed template. The log is as follows:

...

We will end this tutorial creating a report of each ship. Add the folowing relation to create the report:

The WINWORD\$() function will create Word files named Report*.doc. in your report directory and returns the name of this file to Report\$. In multiple case situations a number (*) is added to the name of the document.

So make sure the reports are created, modify Evalution# and add Report\$:
