Scheduling optimization of optical lens polishing
Abstract Optical systems have achieved notable progress in focusing and imaging technologies; however, manual grinding remains indispensable, resulting in elevated costs, extended timelines, and inefficiencies. These difficulties are compounded by operational constraints, uneven machine utilization, and risks of order delays and escalating expenses ...

Heuristic procedures for reactive project scheduling. [PDF]
This paper describes new heuristic reactive project scheduling procedures that may be used to repair resource-constrained roject baseline schedules that suer from multiple activity duration disruptions during project execution.The objective is to ...

Using Fuzzy Multi-Criteria Assessment Method (Fuzzy AHP) in the Best Sequence Selection in a Single Machine Shop [PDF]
One of the main steps in production planning is the operation sequencing. The operation sequencing is assessed by a series of efficiency indexes such as jobs completion average time, jobs maximum tardiness and jobs average tardiness.

The impact of public drop‐off boxes and autonomous delivery robots in last‐mile delivery
Abstract The growing concern over emissions from last‐mile logistics is motivating the development of innovative delivery models aimed at reducing environmental impact and traffic congestion. To this end, we propose a last‐mile delivery scheme based on both public drop‐off boxes and autonomous delivery robots.

An exact procedure for the resource-constrained weighted earliness-tardiness project scheduling problem. [PDF]
In this paper we study the resource-constrained project scheduling problem with weighted earliness-tardiness penalty costs. Project activities are assumed to have a known deterministic due date, a unit earliness as well as a unit tardiness penalty cost ...

This paper addresses the Tardy/Lost penalty minimization on a single machine. According to this penalty criterion, if the tardiness of a job exceeds a predefined value, the job will be lost and penalized by a fixed value.

Bicriteria single machine scheduling to minimize total tardiness and waiting time variance by genetic algorithms [PDF]
Actual scheduling problems may necessitate the decision maker to consider a variety of criteria prior to make any decision. This research considers a single machine scheduling problem, with the objective of minimizing a combination of total tardiness and

Comparative Policy Analysis of Healthcare Healthy Eating Policies in Canada
ABSTRACT Background Healthy eating policies are of growing importance to the management of retail food environments in healthcare (e.g., hospital cafeterias). Several researchers have begun to analyse health promoting benchmarks within these policies. However, little is understood about the relationship between policy and continuous quality improvement

Earliness/tardiness flow-shop scheduling under uncertainty
For unconventional scheduling problems, both job sequence and starting time of every operation must be optimized, which increases the difficulties of solving this kind of problem.

ABSTRACT High‐yield photocatalytic H2O2 production in sacrificial agent‐free pure water constitutes a critical bottleneck requiring urgent advances in energy catalysis. Although ZnIn2S4 (ZIS) exhibits favourable visible light absorption, it is plagued by severe bulk charge carrier recombination and scarce accessible surface‐active sites.
