We investigate a common due-date assignment scheduling problem with a variable maintenance on a single machine. The goal is to minimize the total earliness, tardiness, and due-date cost. We derive some properties on an optimal solution for our problem. For a special case with identical jobs we propose an optimal polynomial time algorithm followed by a numerical example.

Totally implantable venous access port (TIVAP), a novel intravenous infusion system that is used for long-term intravenous treatment, has become increasingly popular among cancer patients undergoing chemotherapy and other patients requiring long-term intravenous infusions. This technology has been introduced into clinical practice in China, with successful results. Nevertheless, there are still certain problems; for instance, China has not set up a specialized regulatory agency to oversee research and set guidelines for the comprehensive life-cycle management of TIVAP.

Purpose: Color imaging is the accepted reference standard for detection of macular fibrosis in neovascular age-macular degeneration. Other imaging modalities of fluorescein angiography (FA) and spectral domain optical coherence tomography (SD-OCT) are also used but no formal agreement studies exist. We evaluated the agreement between fibrosis on colour, FA and SD-OCT-detected hyperreflective material (HRM) and their clinical relevance.
