This section provides details on the more advanced options provided by OMAT:
Data Quality Indicators allow you to provide information on how reliable the data is. It is one possible way of managing uncertainty in Material Flow Analysis. To start using Data Quality Indicators, you need to activate this option in the settings of your project (either when you create the project, or by going to 'Change Settings' in your dashboard).
You can choose to load a predefined set of indicators, or you can define your own. The pre-defined set comes with the following Data Quality Indicators:
Most of these indicators are defined the way they have been defined by Weidema and Wesnæs for Life Cycle Assessments. Each of the indicators will come with a scale between 1-5, and for each of these scores an explanation is provided what this score should represent. However, all of these scores and the indicators can be freely modified to suit your needs. If you want to set up your own set of indicators, then simply load an empty skeleton and take it from there.
Once you have defined the different Data Quality Indicators, you will be able to set them for each of the data points. You will see a new box appear when you enter a new value in the system. This box shows all your indicators and their possible scores. You can set a score by simply clicking the relevant number.
You may be doing the same kind of research on multiple scales. You can for instance study a city, while also doing an MFA on the city-wide region around it. OMAT enables you to use one dataset and create single graphs and tables that contrast the different scales at once. In order to start using multiple scales, be sure you have activated this option in the settings of your project.
Before you can use the multiple scales, be sure to go to Maintenance » Types of Scales. Here, you can add each of the options (for instance 'City of Cape Town', and 'Western Cape Province') as two different scales.
Once this is done, you will see these different scales appear in a dropdown list when you add a data point. For each data point, you will have to select to which of the options it applies.
Performing a Material Flow Analysis is not just about putting down numbers in a spreadsheet and then analyzing the results. The actual process of obtaining this data is often the major part of the work. Finding reliable sources that can provide you with the data you need on the scale you need is a major struggle for many of the MFAs done. OMAT therefore comes with tools that help you keep track of this 'back-office' part of doing an MFA. Be sure to activate this option in the settings if you want to use it.
Contacts are the people and organizations that you use to locate the data that you need. Depending on how easily data is available, you may need to contact people in order to understand where to get the data from, or to request reports that are not publicly available. Similarly, it may be necessary to contact experts who can help with conversion of data or other interpretation or checking of information.
In OMAT you can add a contact and manage the following details:
Similar to how you manage contacts, you can also manage the different documents and other sources that you use. For each source, you can create a record that holds the following information:
If you activate time tracking, then OMAT will provide tools that make it very easy to track how much time you spent on the different activities. You can se the different activities yourself, but among the options are to track time spent on:
To set the activities you want to track, you can go to Maintenance and click on Types of Activities. Here you can add and edit the types you want to track.
Once you have set these options, you can record the time spent on each contact and source. You will see a new box appear, where you can track the time. There are two options to track this: you can either simply enter the time in minutes you spent doing something, or you can start a timer when you initiate and you end it when you finish the activity.
