Challenge

Complex planning

SPF-Selskabet is challenged by a complex set of transport constraints and restrictions. During the planning process, the usual aspects of quality route generation must be taken into consideration, for instance, time windows, capacity limits, access conditions and a number of other qualifications. Besides these, planners must take account of as many as 23 different diseases potentially present on the visited farms.

"Trucks have to be cleaned and disinfected after every completed route, and they must have been quarantined for 12 hours before they leave in the morning", explains Henrik Ringskær. "Still, they have to visit the farms according to a certain disease category schedule throughout the day. To minimize livestock infection, each truck must set out on the farm with the least infected stock and proceed gradually to the farms with more infected animals."

This creates many possible combinations for the planners, resulting in a very complex planning problem. "Because of this high level of complexity, we believed that we would benefit greatly from implementing a planning solution with precise calculation features and automatic route planning functionality."

Solution

The transport operation

Regarding the transport process, Henrik Ringskær explains, "A large number of orders come from permanent agreements between the major pig farmers. Taking these orders as our starting point, we make an optimized base plan. Subsequently, we typically receive a number of last-minute orders up to and during execution, because farmers trade pigs as if they were stocks on the traditional stock market."

"The planning solution enables us to perform automatic insertion of last-minute orders into the plan as well as manual order insertion with tooltips displaying invalid changes if any. This means that we are now able to manage both last-minute and standard orders without any deadlines. The planners are responsible for their own regions", continues Henrik Ringskær, "but with AMCS’ solution, we are capable of carrying out planning across these regions. This means that we can now effectively share resources between regional border areas."

"An additional benefit is that the management team is now able to actively monitor the transport operation. This facilitates the analysis of transport performance on a minute-by-minute basis. We can also run simulations of, for example, the consequences of handling new disease categories or taking in new types of orders and services. Without these modeling capabilities in the AMCS solution, we simply would not have come through our process of reducing costs and improving quality."

Results

Quality and efficiency improvements

In conclusion, Henrik Ringskær notes that "it was difficult to move from manual to automatic planning, and it has necessitated a clear understanding and evaluation of our business and processes."

"However, the result is that we have much fewer errors in our planning today, and we have improved our operations significantly."

Major benefits from implementing the system:

• A reduction of 5-7% in the overall transport costs.
• A centralized planning process including planning across regions.
• An 80% automatic planning process as well as instant calculation of the consequences of manual actions.
• Automatic warnings if the planners break any rules.
• No lost or overlooked orders, increasing the overall transport and customer service quality.
• The ability to make simulations with various cost models.
