	<AimSection><Paragraph>The additional capacity requirements for an item unit in a specific time period, is a value that SSA ERP uses to determine the remaining available capacity of a certain resource. This is one of the steps in the optimization algorithm for logistic parameters in the <GUIRef href="/baanerp/cp/rao" role="module">Resource Analysis and Optimization</GUIRef> module of <GUIRef href="/baanerp/cp" role="package">Enterprise Planning</GUIRef>.</Paragraph>
		<Paragraph>The formula that SSA ERP uses to calculate the additional capacity requirements is:</Paragraph>
		<Formula><Paragraph UserLevel="Novice" UserType="Taskuser">ACR = (R * D) + (S * F)</Paragraph>
		</Formula>
		<Paragraph>Where:</Paragraph>
		<TABLE border="1"><TBODY><TR><TD>ACR</TD>
					<TD>Additional capacity requirements</TD>
				</TR>
				<TR><TD>R</TD>
					<TD>Required capacity per item unit</TD>
				</TR>
				<TR><TD>D</TD>
					<TD>Total demand over the time period</TD>
				</TR>
				<TR><TD>S</TD>
					<TD>Required capacity for setting up the resource</TD>
				</TR>
				<TR><TD>F</TD>
					<TD>Number of times an item is produced in the optimized time period</TD>
				</TR>
			</TBODY>
		</TABLE>

		<Paragraph>Suppose that we have the following data:</Paragraph>
		<TABLE border="1"><TBODY><TR><TD>R:</TD>
					<TD>0.5 hour/piece</TD>
				</TR>
				<TR><TD>D:</TD>
					<TD>600 pieces</TD>
				</TR>
				<TR><TD>S:</TD>
					<TD>1 hour</TD>
				</TR>
				<TR><TD>F:</TD>
					<TD>20</TD>
				</TR>
			</TBODY>
		</TABLE>
		<Paragraph>The calculation of the additional capacity requirements is then:</Paragraph>
		<Formula><Paragraph UserLevel="Novice" UserType="Taskuser">ACR = (R * D) + (S * F) = (0.5 * 600) + (1 * 20) = 300 + 20 =
		  320 </Paragraph>
		</Formula>
		<Paragraph>This means that the additional capacity requirements for all the items of the corresponding plan unit in the involved period is 320 hours.</Paragraph>
