The component sector is used to describe an economic actor, eg public sector, households or private sector. Sectors can be displayed in several layers of the model. See figure below for the layer with real flows.

Cash flows

Identification of the sector, Sector 1. There are two incoming flows of 100 thousand kKr and 400 thousand kKr respectively . FB with orange background indicates that there is flow balance in the sector. Outgoing flow is thus 100 + 400 = 500 thousand. Orange marker on the input streams, highlight that these are prescribed. Blue arrow on the outgoing flow indicates that it is calculated.

Sectors may have an internal structure, sub model, built in the same way as the enclosing model. Opens with the click of text Open.

Sub model appears only with access points to external flows.

Below is a sector with two layers. Payments and real flows of a manufacturing process. For the production materials are purchased and workers  are hired. The profit plus the costs determine which the revenue is needed.

Betalningar = payments, Tillverkning = manufacturing.
Materialkostnad = material cost, Arbetskostnad = work cost, Intäkter = revenues, Vinst = profit.

Reala flöden = real flows
Material = material, Arbete = work, Produkter = products,

The work is measured as worked man-years (wmy). Input materials and products is measured as produced man-years (pmy). With a productivity of 1.0 wmy / pmy needed is a man-years to produce a produktmanår. The boxes with the “P” indicates that prices are prescribed (orange) or calculated (blue).

The relationship between materials, labor, and the amount of products is determined by the sub model for the manufacturing sector.
Manufacturing Process
The circle with “P” designates a process with materials need 0.4 / 1.4 = 0.286 pmy per pmy product and work 1.0 / 1.4 = 0.714 wmy / pmy. Orange diagonals show that the  productivities are prescribed and the orange arrow that the amount of products is given.
