Visual MESA® Supply Chain Scheduling
Almost every company in the process business has the ability to create an economically efficient operations plan to balance supply and demand. Managing scheduled operations through a systematic business process supported by effective analytical tools is crucial to achieve the benefits of optimized operations planning.
The process objective is to:
- Maintain a detailed schedule of operations that follows as close as possible to the planned targets
- Monitor current operations progress and environmental status to capture potentially disruptive events
- Decide if a revision of the planned targets is needed, then replan
- Otherwise asses the impact of events in terms of deviations from planned targets
- And then establish "surgical" modifications to the operations schedule aimed to attenuate the impact of disruptions
Operability Improvements in Event Management: Predict, React, Minimize
The key for keeping adherence to an optimized plan is to:
- Predicts the occurance of disruptive events and therefore to establish proactive actions minimizing further deviations
- Quickly and precisely analyze corrective actions to cope with the occurrence of events that were not anticipated
- To get visibility on the future effect of the corrective actions to be implemented, avoiding that today's solutions become disruptions short after

Support for Collaboration
- Visual MESA Supply Chain Scheduling supports the collaborative scheduling among different users working on an integrated model of the whole supply chain.
- The model is segmented in areas under the responsibility of different decision makers defined through user profiles with read or write permissions to different model areas.
- Every user is allowed to introduce changes only to the enabled area but can analyze the propagating effect of everybody’s scheduling decisions.
- Each scheduler can maintain different schedule scenarios to perform private what-if analysis and collaborate with others to consolidate a unique consensus schedule that is published for everybody to consult.
Dock Scheduling Assignment of Jetties/Berths
- Visual MESA Supply Chain Scheduling Dock Scheduling supports the scheduling and simulation of load/unload operations in berths and jetties.
- The schedule can be managed by editing in a single-click, user-friendly table containing all the detailed operation information: vessel estimated arrival times, vessel data, order data, loading/unloading facilities (berths, jetties and tanks), materials, quantities and rates.
- Timing and allocated resources for the dock scheduling can also be edited through and interactive Gantt diagram allowing “drag and drop” edition.
- It is possible to manage multi-movement (sequential or simultaneous load/unload from/to different tanks) and multi-compartment vessel operations.
- Automation rules are provided to generate ship nominations in order to fulfill feedstock replenishment and products lifting of a given production plan and inventory policy, allocating available berths.
- It provides comprehensive operation reports and can be integrated with other systems such as importing vessel updates from navigation control systems or exporting berth schedule to operation execution system
Blending and Scheduling
- Visual MESA Supply Chain Scheduling provides also detailed model for event-based scheduling of blending operations that allows to capture the logistics aspects of blending facilities
- Is integrated with the production and delivery schedules for end-to-end supply chain analysis, provides rich visualization of blending operation’s outlook and uses simulation to support the detection of disruptive events
Multi-Blend Schedule Optimization
Visual MESA Supply Chain Scheduling Multiblend Schedule Optimization supports the definition of optimal recipes and blend volumes for several products in a window of time.
The recommended volumes and recipes match the supply and demand forecast, meet the constraints regarding storage capacity, product specifications, recipe limits and blending capacity and are decided by minimizing the total cost of the campaign or minimizing the quality giveaway.
Blend properties for products are calculated using non-linear mix equations and the model solution search is based on an MILP solver
