An Atlanta Center sector coordinated a jet direct SUDSY Intersection. I approved the request expecting the aircraft to be on the RNAV STAR. When the pilot checked in I verified his speed and he reported 250 KTS. I later asked the pilot whether or not he was descending via our OPD and he responded no. I expected him to make the downwind turn at AMOBE; when he didn't I issued the aircraft a correcting vector then noticed that he had slowed to 200 KTS without advising me. I advised him to increase speed. I tried to turn and slow the OPD arrival behind the Business Jet; but the reaction was not only too late but incorrect. Many factors went into my confusion in this scenario. The Center Controller never specified the arrival routing for the Business Jet; and I should have made him. The aircraft never reported slowing from his assigned speed. Had the pilot been at his assigned speed this event could have been prevented. Pilots reducing speed without notification is an all too common occurrence at CLT. I should have made further inquiries to the pilot about his assigned arrival.
10;000 FT; 10 DME Fix on MAJIC1 Arrival. NO speed requirements beyond 250 KTS at MAJIC fix. Slowed aircraft to 210 KTS to prepare for descent. No previous speed had been assigned. Increased to 230 KTS and shortly thereafter given vectors to 180 heading and descent to 6;000 FT. I asked if they needed a speed and was given 170 KTS with a right turn to 270; and then given a right turn for visual 36R at CLT.
Controller assumes aircraft is on RNAV approach; doesn't verify arrival assignment with pilot and has an operational error due to lack of speed control.
