DBRS Simulation Model for Elastic Service Capacity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Drum-Buffer-Rope (DBR) feedback mechanisms are limited in service enterprise environments with elastic capacity, failing to effectively manage demands on service resources based on such elastic capacity.
Innovation Solution
The Drum-Buffer-Rope for Services (DBRS) model is introduced, which simulates service processes by populating a DBRS model with user-selected values for a constraint drum, pre-constraint buffer, service level rope, and constraint rope to determine compliance with Service Level Agreements (SLA), enabling capacity management and resource allocation in response to demand changes.

Engineering Contradiction Analysis
1Productivity
If DBR feedback mechanism is used in service enterprise environment, then service process management is improved, but it fails to effectively manage demands on service resources based on elastic capacity
Solution Approach 1:
The patent applies dynamics by transforming the static DBR feedback mechanism into a dynamic simulation model that can adapt to elastic capacity in service environments. The simulation model dynamically adjusts to varying service resource capacities and demand patterns, allowing the system to effectively manage demands based on elastic capacity while maintaining improved service process management efficiency.
2Ease of manufacture
If service capacity is assumed to be fixed, then DBR concepts can be applied, but it cannot effectively manage elastic capacity and demand changes
Solution Approach 1:
The patent applies copying by creating a virtual simulation model that replicates the service process environment. This simulated environment allows DBR concepts to be applied and tested with fixed capacity assumptions while the actual system maintains elastic capacity. The simulation copy enables effective management of elastic capacity and demand changes without losing the simplicity of DBR concept application.
3Productivity
If traditional DBR is used in manufacturing environment, then bottleneck management is effective, but it cannot be directly applied to service enterprise environment with elastic capacity
Solution Approach 1:
The patent applies universality by developing a simulation model that makes the DBR feedback mechanism universally applicable to both manufacturing and service environments. The model maintains the core bottleneck management effectiveness of traditional DBR while adding the capability to handle elastic capacity characteristics of service enterprises, thereby achieving multi-functionality across different enterprise types.

AI summary
In order to apply and incorporate Drum-Buffer-Rope (DBR) concepts into a service enterprise environment, the present invention provides a method, system and computer-readable medium that expands DBR through the use of simulation of service activities. In a preferred embodiment, the inventive method includes the steps of: creating a DBR for Services (DBRS) model of a service process; simulating the service process by populating the DBRS model with user-selected values for a constraint drum, a pre-constraint buffer, a service level rope, and a constraint rope, and determining if the service process will be in compliance with a Service Level Agreement (SLA) based on a DBRS simulation of the service process.
