SC Navigator

Hi all!I built a feasible model in SG Navigator with 21 production plants and a detailed BOM per item and location. However, I must add constraints related to the total production per item and location during the period of analysis. I tried three ways but any of them worked: Adding Minimum capacity and Force Open = 1 in the Production Sheet + Adding Minimum capacity per Location and Item in the Production Routing Sheet. Result = The model was infeasible  Adding Maximum capacity in the Production Sheet + Adding Minimum capacity per Location and Item in the Production Routing Sheet. Result = The model does not respect all of the constraints  Adding Minimum capacity and Maximum capacity (both of them with the same quantities) in the Production Sheet +  Production Routing Sheet. Result = The model was infeasible How should I model those constraints? Thanks!  

Whiteboard in SC NavigatorHi all, I am very happy to share a new feature which is available for all SC Navigator users: Whiteboard.Users start by drawing the supply chain network just like you would with a marker on a physical whiteboard, except the whiteboard is made available digitally within SC Navigator. The feature allows users to draw a digital version of the network by using rectangle shapes for entities such as – suppliers, production facilities, warehouses, and customers, and connection lines for transport lanes. Additional data, like capacity and costs, can be easily attributed to an entity via a table.Once done, with a click of a button, the drawing and tables are translated into rows and columns in an Excel template. The Excel template can be uploaded into SC Navigator and all entities and transport

In response to the increasing demand for agile scenario planning within shorter time frames, AIMMS has recently integrated the Tactical Planning module in SC Navigator. The addition of this module addresses the need for tactical decision-making in supply chain network design, focusing on shorter horizons and smaller time buckets, typically ranging from 3 to 24 months.Tactical planning enables businesses to adapt to sudden changes and disruptions while maximizing existing resources. It empowers companies to flex their networks on a monthly basis, efficiently managing both planned events such as maintenance shutdowns and unexpected disruptions, without solely relying on large capital expenditures.The primary objective of tactical planning is to optimize network utilization without significant capital investment. For instance, if demand spikes,

Brazil’s tax system poses a daunting challenge for companies due to its intricate regulations, multiple layers of taxes, and diverse regional variations. The vastness of the country leads to significant regional disparities where states and municipalities boast distinct tax incentives, rates, and regulations. This diversity complicates efforts for companies operating across multiple regions to unify and streamline their tax strategies effectively. AIMMS’ focus on Brazil’s tax challengesAIMMS serves companies either based in Brazil or actively engaged in business within the country. Discovering unique solutions for navigating the intricate Brazilian tax landscape has, therefore, been a focal point for AIMMS, reflecting a commitment to addressing the complexities of this particular system. Our journey began with the development of functionality tailored to handle refundable taxes – a distinctive feature within Brazil’s tax framework

For the Network Optimization project on which I am working, the decision makers want to measure “Warehouse Utilization”, i.e. how full are the warehouses. Assume Utilization = cubic feet of inventory / cubic feet of warehouse space.However, Network Optimization measures throughput flow, not [static] inventory space used, so flow has to be converted to space somehow. We could use a conversion factor like the following: Space to Flow ratio = Average Inventory / Total Throughput.The ratio could be calculated on a monthly (or annual) basis using Total Throughput = Sales and Average Inventory = (Starting Inventory + Ending Inventory) / 2. (Inventory snapshots would be pulled from the company’s warehouse management system.)Someone else on the project team thinks we could (with a multiperiod model) calculate the following: Utilization = Ending Cubic Inventory / Warehouse Cubic Space. I think this is wrong because this ending inventory

Hi,Is it possible to assign customers to multiple groups? For instance, I want to have customer groups based on sales channel and geography. Each customer needs belong to a channel group and a geography group.Many thanks

Hi,I recently started using SC Navigator and am experiencing issues loading my dataset to the app. When I try to load the Excel file (attached) for a Network Design model problem, the app displays an error as shown belowWhere I could I be going wrong here? I checked for duplicates within the excel and there don’t seem to be any. Appreciate the help!Thanks

I am building a SC Navigator model with many customers with each customer having multiple locations. I require model to source all products for all customer locations within a customer from a single DC. Could you please help with right configuration and data prep to make it happen?
