A Novel Dynamic and Fuzzy Value Stream Mapping (DFVSM): System Dynamics and Fuzzy Logic Integration

Value stream mapping (VSM) is a method to identify waste and activities that do not add value. One of its main disadvantages the parameters used in process material flows are deterministic. The motivation this research improve reliability estimation lead time VSM, transitioning from static model dynamic incorporates uncertainty imprecision data, as well develop novel fuzzy value (DFVSM) based on integrating system dynamics logic. contributions same interface vagueness efficiency effectiveness percentage variable (OEE%) increase delivery planning. stages DFVSM explicitly described applied real data for textile company southern Guanajuato. A sensitivity analysis proposed was integrated which identifies critical factors order, achievable times were supplier client, thus reducing expected by 28%. relevant conclusions work that, plan an such customer shipping be considered satisfy customer.
