Production Planning in Marine Industry
Italy is historically known for being one of the most exclusive countries to produce yachts and super yachts across the globe. In order to gain market penetration amongst the numerous prestigious brands, cost control and rightsizing are as important as product and process innovation. The manufacturing process of luxury yachts is complex, and the quality of the final product and craftsmanship cannot be compromised. The manufacturing process requires a huge amount of time and labor for each yacht.
Each yacht uses a multitude of different highly skilled trades, performing a large number of manufacturing tasks, some of which can be completed in sequence, and others that are mutually exclusive. To add to the complexity, the process is constrained by space, both in terms of how many yachts can be in the factory at any one time (at over 60 feet, the logistics associated with moving a yacht around the factory isn’t easy), and in terms of how many people can be working on the yacht at once (it is impossible to have a horde of people working within the same hull at the same time).
The managers of one of the most important Italian manufacturers needed a new, intelligent approach that would make the planning process simpler. Fair Dynamics and DSE Consulting were approached to develop a radical new tool for simulation support planning. The objective was to give the real production planner exceptionally rich planning information, which would allow the person to test and refine a plan before its implementation. The concept of the tool was guided decision making, which means that the individual can easily refine ideas and test a plan’s feasibility over multiple simulations before rolling it out to the factory.
The solution was a simulation based decision support tool developed through AnyLogic, using its unique hybrid approach. Discrete events were used to model the physical layout and the manufacturing process, and Agent Based were used to model the production planner’s complex and adaptive “day-by-day” decision making. This tool could easily simulate both automatic (Agent Based decision making) and human guided planning solutions as an integral part of a 3 step aggregate plan process:
- Automatic, unconstrained scheduling.
- Human guided review of both the master plan and the resource plan, adjusting parameters.
- Constrained production planning, using the updated data from stage 2, to tests its feasibility.
Thanks to the efficient Anylogic Java engine, the entire simulation process of a production season only took a few seconds!
- Strong increase of resource planning process productivity.
- Efficient distribution of resource tasks.
- Human resource cost saving.
- Manager’s time saving.
- A better management support to resource allocation concerns.

Shipyard Capacity AnalysisWith AnyLogic simulation software as the centerpiece, NASSCO utilizes a custom-built analysis system called the Large Scale Computer Simulation Modeling System for Shipbuilding (LSMSe) to provide highly detailed and accurate capacity analyses for both current production and potential new work.
Modeling of Banca d'Italia Back Office SystemBanca d'Italia processes a certain amount of manual credit transfers every year. These transfers cannot be processed automatically and require two divisions of employees in the back office of the bank. The bank wanted to determine if merging these two divisions would be beneficial.
Simulating Ice Cream Production: Recognizing Constraints and Optimizing Production PlanConaprole, the biggest dairy production company in Uruguay, produces more than 150 SKUs in their ice cream plant, using five production lines, and up to five different packaging configurations for each line. The management’s challenge was to be able to reformulate their plans in order to balance supply and demand and make sure they would avoid stock-outs in key products. They also sought ways to optimize the use of their production capacities.
Simple Simulation Model Helps Intel Avoid Production Plant DowntimeIntel factories used a particular type of equipment that often broke down, which caused capacity constraints. These expensive parts were used in critical factory operations, and the repairs took significant time, so it was necessary to have extra spare parts on hand to avoid downtimes. Broken parts caused constraints at some of the factories while other factories over purchased spares.
Construction Simulation Model Tackling Increased Constraints on a Complex Earthmoving Project“Anylogic’s flexible and easy to use environment enabled CCT’s simulation engineers to rapidly model the newly added constraints and deliver a valuable simulation model leading to a highly successful claim process,” affirms Ramzi Roy Labban, Manager, Construction Systems and Simulation at CCC.
Improving Plane Maintenance Process with AnyLogic Agent-Based ModelingThe military aircraft maintenance turnaround process (the in-between time when the aircraft touches down, is refueled, rearmed, and inspected, in order to be released) is complex and, being fairly time-consuming, includes multiple interactions and parallel workflows. Engineers from Lockheed Martin, one of the largest companies in the aerospace, defense, security, and technologies industry, used AnyLogic simulation modeling to improve decision making in the entire military airplane turnaround process and evaluate the impact of process changes on turnaround time.
Business Processes Optimization Using Data Science and Simulation ModelingThe world’s largest companies use data analytics to increase their revenue and keep up with the changing business world. But how does data science relate to simulation modeling, and what are the cases for the implementation of this interaction, primarily concerning value for the business? The United Services Automobile Association (USAA), a Fortune 500 group of companies, has answered these questions with real-life solutions.
Outpatient Appointment Scheduling Using Discrete Event Simulation ModelingIndiana University Health Arnett Hospital, consisting of a full-service acute care hospital and a multispecialty clinic, faced poor statistics because the number of no-show patients (those who don’t show up for their scheduled appointments) rose dramatically to 30%. This was primarily connected to the fact that clinic schedules were driven by individual preferences of the medical staff, which led to increased variations in scheduling rules. To eliminate the problem, the client wanted to develop a scheduling methodology that would benefit the clinic, doctors, and patients.
Improving Mining Outbound Logistics with Agent-Based Simulation ModelingOne of the largest resource companies in the world, with over $80 billion in sales, decided to enter a new market. It was planning to build a new potash mine with 90% of the resources exported. They wanted to design a reliable supply chain, with a high speed of supply replenishing, and the ability to recover from natural disasters and man-made crises benefiting from such volatility. Amalgama and Goldratt companies contracted this project to design the potash mining operations and a full supply chain of outbound logistics.
