The re-emergence of H1N1 influenza virus in 1977: a cautionary tale for estimating divergence times using biologically unrealistic sampling dates. [PDF]
PLoS ONE, 2010 In 1977, H1N1 influenza A virus reappeared after a 20-year absence. Genetic analysis indicated that this strain was missing decades of nucleotide sequence evolution, suggesting an accidental release of a frozen laboratory strain into the general ...

A New Formulation for the Single Machine Order Acceptance and Scheduling Problem with Sequence-Dependent Setup Times [PDF]
International Journal of Supply and Operations Management, 2019 Order acceptance and scheduling problem consists of simultaneously deciding which orders to be selected and how to schedule these selected orders.

KPI Science News, 2021 Background. In setting a problem of minimizing total weighted tardiness by the heuristic based on remaining available and processing periods, there are two opposite ways to input the data: the job release dates are given in either ascending or ...

Blocking Flowshop Scheduling Model for Optimising Cubic Criterion With Release Dates
IEEE Access, 2018 Blocking phenomenon occurs in a flowshop that has a limited buffer between any two successive machines. Once the buffer is full, the upstream machine is forbidden to release a finished job.

Adjusting scheduling model with release and due dates in production planning
Cogent Engineering, 2017 Motivated by the conjecture that an interaction between scheduling and pre-scheduling phases in production planning may give certain benefits, we conduct a detailed study of the optimality conditions and dominance relations for a strongly NP-hard single ...
