Optessa MLS: Detailed Sequencing and Scheduling

MLS is Optessa’s Detailed Sequencing and Scheduling software

Optessa MLS is Optessa’s advanced detailed sequencing and scheduling solution for a wide range of manufacturing industries.

In a highly competitive environment, manufacturers want to maintain and increase market share by controlling costs, improving throughput and reducing order to delivery lead time.Effective sequencing and scheduling can help meet all the objectives, which makes manufacturing sequencing / scheduling a process of strategic importance.

Optessa MLS is specifically designed to address the complex sequencing and scheduling requirements of manufacturing industries with product variety, large volumes and multiple lines/ plants. Optessa MLS generates high quality, near optimal sequences and schedules.

Optessa MLS has an established track record of enabling manufacturers to reduce order to delivery lead times, reduce inventories, and smooth production to fulfill each order while reducing manufacturing costs.

The quality and evenness of an Optessa MLS solution is vastly superior to a solution generated by other techniques. The Optessa MLS optimization engine  can generate a near optimal solution after considering all the rules and constraints. Based on modern optimization techniques and embodying patented algorithms, the computational engine optimizes the entire solution.

The quality of an MLS solution is evenly favorable without deterioration in the later part; hence there will be no uneven lumps at the end of each day or month. The following comparison of the sequencing of 1200 orders using Optessa MLS and a legacy system highlights the superiority of the Optessa MLS solution.

Legacy System
Optessa MLS

The sequence generated by the legacy system is of uneven quality, and the constraint violation it generated are visible in the form of spikes in the chart. The Optessa MLS sequence has almost no spikes; moreover it is of an evenly favorable or smooth  quality.

The manifold strengths of Optessa MLS come from its superior technology, the deep domain knowledge and expertise that have gone into the product, as well as the highly evolved, easy to use design of its user interface. Here are some of the key strengths of Optessa MLS:

Powerful Optimization Engine

Optessa MLS uses state-of-the-art optimization techniques that are vastly superior to legacy or manual systems. As a result, the system produces complete, near optimal solutions with fast execution times.

Comprehensive, flexible and easy to use approach to rules and constraints
  • MLS considers all rules and constraints; users can prioritize constraints by assigning a priority ranking or weight.
  • MLS supports a large and comprehensive set of rules and constraints; it is also readily extensible if a new constraint is encountered.
  • MLS simplifies rule and constraint definition.
  • The system allows constraints to be specified in terms of weekly / daily / hourly bins or buckets.
  • Defining constraints is simple in Optessa MLS. Each constraint has a time window within which the constraint is effective; a priority or weight can be associated with each constraint to indicate its importance; and the user also has a choice of how a penalty will be applied if a constraint is violated.
Comprehensive and correct treatment of violations
  • Violations, if inevitable, are smoothed and balanced.
  • Different types of penalty functions are supported.
Users define units, line and feature capacity

Optessa MLS lets the user organize units at arbitrary levels: you may choose to organize the sequence in single units, small or large lots or batches.

Optessa MLS also allows an equally flexible definition of line capacity: the system expresses line capacity in terms of

  • Slots per week / day / shift / hour, OR
  • Available time by shift patterns, OR
  • Combinations of both

The user can choose a different line capacity for each day or other time bins; the system allows empty slots so you can easily accommodate changing line capacity from – say 5000 units this week to 4000 the next and then 7000 the week after.

Optessa is flexible and easy to use in many different ways

Superior graphics allow users to view and manipulate the sequence. MLS gives the user the flexibility to swap/ move orders or lots manually within a sequence. The user can interactively swap a pair of lots in the sequence and the system will immediately report the new penalty cost.

Visualization charts allow the user to focus on parts of the sequence that have violations and then drill down to the sequence viewer.

The user interface can be accessed with a web-browser, and the system allows easy integration with other business systems.

MLS allows you to run and store any number of what-if / simulation scenarios and compare them before committing to a particular solution.
